Audio Formats

Audio Cassette
Maybe you have some of your voice when you were a child? Maybe you have some voice on a cassette of a long since passed relative?

The audio cassette (aka compact cassette) was produced by Philips in 1962. The magnetic tape is 3.81mm wide with each stereo track 0.6mm wide. The tape moves at a constant speed of 4.76cm per second from left to right. The format overtook the vinyl LP to become the most common/popular audio format in the 1970s and early 1980s until it was overtaken by the CD.
1/4" Reel to Reel
In the old days before Audio Cassette, All personal recordings were recorded on this popular format.

1/4" open reel or quarter inch audio reel to reel was first introduced in 1948. It became popular for both consumer products and professional recordings, whilst consumer products were replaced by the audio cassette. 1/4" consumer audio tapes could be 1 7/8ips, 3 3/4ips or 7 1/2ips. Professional recordings were generally done at 7 1/2ips or 15 ips. DVD Infinity will use a deck and speed appropriate for your 1/4" reel to reel recording. We will then ensure that the signal from the audio reel is optimised to get the very best out of it. Noise reduction is applied to get the very best out of the recording
LP records contain much of Australia's early audio recordings. Whilst Australian copyright law prohibits the conversion of materials for which you do not own the copyright, we can certainly transfer your home made LPs (33, 45 and 78rpm) - laminated, shellac, lacquer, glass, steel, cardboard or aluminum records to CD or Files. Obviously if you own the copyright to commercial material, then we can transfer those LPs as well.
Maybe someone left something funny on your answering machine once and you kept it?

Originally introduced by Olympus in 1969, using thin magnetic coated tape and half or a quarter the tape speed, microcassettes offer comparable recording time to the audio cassette. Microcassette was popular with dictation machines and answering machines. It was also used in computer storage due to its size. DVD Infinity will use the best deck available and optimise the audio signal to get the very best from your audio recording.
Mini Cassette
It was normally only used for dictaphone and transcription.

Originally introduced by Philips in 1967, using thin magnetic coated tape. The recording was only ever good for recording voice as its construction meant that the recording speed was not constant. The Minicassette was popular with dictation machines and answering machines. It was also used in computer storage due to its size.
It is also referred to as MD.

The MiniDisc (MD) is a magneto-optical disc-based data storage device offering a capacity of 74 minutes and, later, 80 minutes, of digitised audio or 1 gigabyte of Hi-MD data. The Sony brand audio players were on the market from September 1992 until March 2013. The music format was based on linear PCM digital recording to attain audio quality comparable to that of a compact disc. MiniDiscs were very popular in Japan but made a limited impact elsewhere.
Usually, this format is used for professionally recording in studio.

In 1987, DAT tapes became the defacto standard for recording professional audio. DAT tapes use 4mm magnetic tape inside a 73mm x 54mm x 105mm shell (about the size of a miniDV tape). DAT tapes can run from 15 mins to 180 mins. DAT was also used as a data storage mechanism. DAT superceded the process of recording audio digitally using PCM to Betamax, VHS or U-matic tapes.
In 1991, Alessis introduced ADAT for recording professional audio of 8 tracks of audio onto a SVHS tape.
PCM Audio
Usually, this format is used for professionally recording in studio.

PCM Audio was a popular way of recording professional digital sound in the early 1980s. It is recorded PCM Audio recorded on Betamax, VHS, U-matic or Beta SP.
