1.the differences is that analog audiotape recording,electrical signals are transduced into magnetic signals at the recording stage and encoded onto tape,and digital is recording signals into a digital format for recording involves a series of steps .
2.the widths are 1/4,1/2,1,and 2inch.
3. never handle the tape surface- front or back, don’t smoke or eat in the tape area, carry the tape reel by the hub, trim damaged tape ends to avoid depositing debris on the tape transport and record heads and always store tape in a dust-proof container when it is no tin use.
4. slow changes are called wow and faster changes are called flutter. if a problem results from any change in the constant transport speed during a recording or playback, the sound may take on audible changes in frequency.

1.In electronics, a digital-to-analog converter (DAC or D-to-A) is a device for converting a digital (usually binary) code to an analog signal (current, voltage or electric charge).
2.Since the widespread adoption of reel-to-reel audio tape recording in the 1950s, audio tapes and tape cassettes have been available in many formats. This article describes the length, tape thickness and playing times of some of the most common ones.
3.These notes were intended only for myself and family but others seem to find them useful too so here they are for everyone.
MOST of us save our music in either (a) WAV files or (b) MP3 files.
WAV files are large but for an “audio CD” to play in most CD players or vehicle CD players, you need “audio CDs” on which the music must be in WAV format.
4.is carried out on audio tape machines, cassette recorders and players, and other analog recording and reproduction devices with rotary components (e.g. movie projectors, turntables (vinyl recording), etc.).
5. is a term used to describe a tendency or preference towards a particular perspective, ideology or result, when the tendency interferes with the ability to be impartial, unprejudiced, or objective
6.Sample rate conversion is the process of converting a (usually digital) signal from one sampling rate to another, while changing the information carried by the signal as little as possible. When applied to an image, this process is sometimes called image scaling.

1.) In analog recording, the waveform of the signal being processed resembles the waveform of the original sound; they are analogous. The frequency and amplitude of an electrical signal changes continuously in direct relationship to the original acoustic sound waves; it is always “on”. Although the digital recording process is entirely different, the tape medium and some of the tape recorders used in analog and digital recording have a number of features in common.
Analog recording is made on tape and digital recording is made on the computer.
2.) Open-reel audiotape comes in four widths: 1/4, 1/2, 1, and 2 inch. Analog cassette tape is roughly 3/20- inch wide. For the most part, only the 2-inch width is used professionally in analog recording today.
3.) Don’t smoke or eat in the tape area. Smoke and food particles can contaminate the tape and also cause damage.
— Carry the tape reel by the hub
— Trim damaged tape ends to avoid depositing debris on the tape transport and record heads.
— Always store tape in a dust-proof container when it is not in use.
— Don’t stack tapes on top of one another. Store tapes vertically so they will be supported by the hub.
4.) Constant tape movement and tension are critical to acceptable recording. If a problem results from any change in the constant transport speed during recordings or playback, the sound may take on audible changes in frequency. Slow changes are called wow ; faster changes are called flutter.
5.) Before examining the function of each magnetic head,it is necessary to discuss bias. The response of magnetic particles on recording tape is non-linear– their magnetic energy isn’t a perfect analog of the signal from the record head.
6.) Sampling takes periodic samples of the original analog signal at fixed intervals and converts them to digital data.The sampling rate, sample rate, or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete signal. For time-domain signals, it can be measured in samples per second (S/s),[1] or hertz (Hz).[2] The inverse of the sampling frequency is the sampling period or sampling interval, which is the time between samples.[3]
The concept of sampling frequency can only be applied to samplers in which samples are taken periodically. Some samplers may sample at a non-periodic rate.
The common notation for sampling frequency is fs which stands for frequency (subscript) sampled.
7.) Quantization is the process of converting a continuous analog audio signal to a digital signal with discrete numerical valuesIn a compact disc, an analog recording is converted to a digital signal sampled at 44,100Hz and quantized with 16-bits of data per sample.
— in analog recording , the wave form of the as signal being processed resembles the wave form of the original sound.

1- Analog recording is a method in which the the waveform of the recorded signal resembles the waveform of the original signal. Digital recording is a method of recording in which samples of the original analog signal are encoded as pulses and then decoded during playback. The most widespread today i think is digital recording.
2- The width of the open-reel audiotape is available in is 1/4, 1/2, 1, and 2 inch.
3- Five ways to properly handle audiotape are no smoking or eating in the tape area, carry the tape by the hub, always store tape in a dust-proof container when it is not in use, don’t stack tapes on top of one another, and keep tape away from heat-generating equipment and magnetic fields when not in use.
4- Wow are slow changes and flutter are faster changes in sound. It is caused if a problem results from any change in the constant transport speed during recording or playback, the sound may take on audible changes in frequency. Wow and flutter are usually not a problem with regularly maintained professional equipment. If either or both are present in recording, however, it may be not audible on the original tape.
5- Bias is the inaudible DC or AC signal added to an audio signal to overcome nonlinearities of amplification or the medium. In magnetic-tape recording, ultrasonic AC bias is used to linearize the tape medium, which would otherwise be highly distorted.
6- Sampling is examining an analog signal at regular intervals defined by the sampling frequency. A process whereby a section of digital audio representing a sonic event, acoustic or electroacoustic, is stored into disk or memory. The common sampling rates are 20 kHz or 40 kHz.

In electronics, a digital-to-analog converter (DAC or D-to-A) is a device for converting a digital (usually binary) code to an analog signal (current, voltage or electric charge).
An analog-to-digital converter (ADC) performs the reverse operation.
Since the widespread adoption of reel-to-reel audio tape recording in the 1950s, audio tapes and tape cassettes have been available in many formats. This article describes the length, tape thickness and playing times of some of the most common ones.
Reel-to-reel, open reel tape recording is the form of magnetic tape audio recording in which the recording medium is held on a reel, rather than being securely contained within a cassette.
Wow and flutter measurement is carried out on audio tape machines, cassette recorders and players, and other analog recording and reproduction devices with rotary components (e.g. movie projectors, turntables (vinyl recording), etc.). This measurement quantifies the amount of ‘frequency wobble’ (caused by speed fluctuations) present in subjectively valid terms. Turntables tend to suffer mainly slow Wow. In digital systems, which are locked to crystal oscillators, wow and flutter are usually significantly more subtle, and are referred to as jitter.
Bias is a term used to describe a tendency or preference towards a particular perspective, ideology or result, when the tendency interferes with the ability to be impartial, unprejudiced, or objective.[1]. In other words, bias is generally seen as a ‘one-sided’ perspective. The term biased refers to a person or group who is judged to exhibit bias. It is used to describe an attitude, judgment, or behavior that is influenced by a prejudice. Bias can be unconscious or conscious in awareness. Having a bias is part of a normal development. Labeling someone as biased in some regard implies they need a greater or more flexible perspective in that area, or that they need to consider more deeply the context.
ample rate conversion is the process of converting a (usually digital) signal from one sampling rate to another, while changing the information carried by the signal as little as possible. When applied to an image, this process is sometimes called image scaling.
Quantization is the procedure of constraining something from a continuous set of values (such as the real numbers) to a discrete set (such as the integers). Quantization in specific domains is discussed
a method of sound recording in which an input audio waveform is converted to an analogous waveform.
a record or tape made by this method.
Telecommunications. the smallest range of frequencies constituting a band, within which a particular signal can be transmitted without distortion.
Biasing in electronics is the method of establishing predetermined voltages and/or currents at various points of a circuit to set an appropriate operating point .

In analog technology, a wave is recorded or used in its original form. So, for example, in an analog tape recorder, a signal is taken straight from the microphone and laid onto tape.
Since the widespread adoption of reel-to-reel audio tape recording in the 1950s, audio tapes and tape cassettes have been available in many formats.

1.This one is thicker and the other one is less thicker and i think digital is more widespread
2. 1/4,1/2,1,and 2 inch.
3.It never handle’s the tape surface,use lint-free gloves,avoid depositing debris on the tape,carry the tape reel by the hub,
4.WOW! is slow changes and flutter is faster changes and the sound may take on audible changes in frequency.
5.It is the response of magnetic particles on recording tape.
6.Sampling takes periodic samples of the original analog signal at fixed intervals converts them digital data. And sampling frequency is the rate.
7.Quantization is when voltages are converted into discrete quantities and assigned values.
VOCABULARY

*analog recording:a method of recording in which the wave form of the recorded signal resembles the wave form or the original signal.
*digital recording: a metod of recording in which samples of the original analog signals are encoded as pulses and then decoded during playback
*audio data rate:a technique used to rerecord dialogue in synchronization with picture in post production. The pictures automatically replayed in short loops again and again so that the performers can synchronize their lip movements with the lip movements in the picture and then record the dialogue also known as automatic dialog recording and looping
*bandwidth:the difference between the upper and lower frequency limits of an audio component. The upper and lower frequency limits of am radio are 535 and 1605 kHz; there for, the bandwidth of am radio is 1070 kHz.
*bias current:an extremely high frequency ac current, far beyond all debility, edited during a tape recording to linearize the magnetic information
*calibration: adjusting equipment-for example, a console and a recorder- according to a standard so that their measurements are similar.
*digital audiotape: the cassette tape used with the rotary-head digital audio tape recorder. It is about one eighth inch wide, about one fourth mil thick, and about one fourth the length of an analogue cassette audiotape.
1) What is the difference between analog and digital? Which is more widespread today?

1) What is the difference between analog and digital? Which is more widespread today? The format is virtually noise-free; sound quality is crystal clear; many copies of the original recording can be made without loss in sound quality; data storage and production flexibility are substantially.
2) What are the widths that audiotape is available in? Open-reel audiotape comes: 1/4, 1/2, 1 and 2 inches.
3) Name 5 ways to properly handle audiotape.
1. Keep tape away from heat-generating equipment and magnetic fields when not in use.
2. Do not stack tapes on top of one another. Store tapes vertically so they will be supported by the hub.
3. Always store tape in a dust-proof container when it is not in use.
4. Trim damage tape ends to avoid depositing debris on the tape transport and record heads.
5. Carry the tape reel by the hub.
4) What is wow and flutter? How is it caused? If a problem results from any change in the constant transport speed during recording or playback, the sound may take on audible changes in frequency.
5) What is bias? Before examine the function of each magnetic head, it is necessary to discuss bias.
6) What is sampling? What are the common sampling rates used in digital audio?Takes periodic samples (voltages) of the original signal at fixed intervals and converts them to digital data.
7) What is quantization?As sample of the wave form are taken, these voltages are converted into discrete quantities and assigned values, a process.
Define the following terms:
1. analog recording: A method of recording in which the waveform of the recorded signal resembels the waveform of the original signal.
2. digital recording: A method of recording of the original analog signal that are encoded as pulses then decoded during playback.
3. Audio data rate: A relationship of sampling rate and quantization.
4. Bandwidth: The difference between the upper and lower frequency limits of an audio component.
5. Bias current: An extremely high frequency AC current,far beyond audibility , added during a tape recording linearize the magnetic information.

1.the differences is that analog audiotape recording,electrical signals are transduced into magnetic signals at the recording stage and encoded onto tape,and digital is recording signals into a digital format for recording involves a series of steps .
2.the widths are 1/4,1/2,1,and 2inch.
3. never handle the tape surface- front or back, don’t smoke or eat in the tape area, carry the tape reel by the hub, trim damaged tape ends to avoid depositing debris on the tape transport and record heads and always store tape in a dust-proof container when it is no tin use.
4. slow changes are called wow and faster changes are called flutter. if a problem results from any change in the constant transport speed during a recording or playback, the sound may take on audible changes in frequency.
5. the inaudible DC or AC signal added to an audio signal to overcome nonlinearities of amplification or the medium
6. is the periodic samples of the original analog signal at fixed intervals and converts them to digital data. the most common are 32, 44.056, 44.1, 48 and 96 kHz
7. converting a waveform that is infinitely variable into a finite series of discrete levels
