Analog Recording

1945

Analog recording was introduced to the United States in

1948, three

In ___ the first ___ track recorder was introduced

corresponding magnectic energy that can be stored onto tape in the form of magnetic remnants

An ATR can transform an electrical input signal directly into a

corresponding electric signal that can be amplified, mixed, processed and heard

Upon playback, magnetic energy is then converted back into a

Antistatic Backing 

Polyester Base (PVC)

Magnetic Oxide 

Tape Coating

A 4 layer recording medium consists of

1/4”, 1/2”, 1”, and 2” formats for recording purposes

Tape typically comes in

individual record and playback regions that correspond to each track on the ATR

The headstack consists of

2, 4, 8, 16, and 24 track configurations

The headstack typically comes in

In the headstack, there are typically a

“record” stack, “playback” stack and an “erase” head 

A gap in it

An electrical signal is routed to an individual region of the record head that has 

the particles of magentic oxide are aligned on the tape to represent the waveform 

The magnetic tape medium completes the electrical circuit as it passes over the gap and the audio is stored when

the magnetic flux stored on the tape medium creates the same electrical current in the stystem that was stored in the reverse process

When tape is run back iver the “playback head”

The wider the available dynamic range, the lower the noise flor and the higher the fidelity 

The more magnetic particles available to align on the tape, whether by wider tape or smaller head count

Transport

the tape speed

An important feature of transport is

7 ½

inches per second (IPS)

Recorders usually operate at speeds of

How many particles of magnetic oxide are available to capture the electronic signal

In conjunction with track width, the speed will also determine

The elements of the ATR system that convert and faciliate transition of the input signal to and from the head stacks 

Electronics

there is an occurence of higher frequency sounds not being captured as well on tape since their wavelengths are equal to or smaller than the width of the head gap on the head 

Due to the phenomenon of frequency wavelengths getting shorter and shorter as they increase,

boosts the high frequencies by 6db per octave to acheive a flat playback response

Because of this, there is an EQ curve automatically applied that

30 IPS; 16 tracks; 2 reels of tape

Most modern tape machines run at ____ and contain ______ on _____ reels

30 IPS; 2 Tracks , 1/2” of tape

Mixdown decks are typically ___ IPS and ___ tracks on ____” of tape

Vintage. It would be bigger, more compressed and bassier with a slightly higher noise ceiling

At times, a 15 IPS setting is selected because the sound is more
