¼” (quarter inch) 4 track format was made for home quadraphonic stereo and later by musicians. We can transfer your 4 track reels to digital .wav or .aiff files.

Domestic machines were usually four-track (also called quarter-track) in that they recorded in both directions, providing double the amount of recording/playback time by allowing you to flip the tape over between side A and side B – though remember we’re not actually talking about two physical sides as with vinyl, since tape only has one recordable magnetic surface. So a four-track/quarter-track tape records two channels in one direction and two in the other when the tape is turned over, each track occupying a quarter of the total tape width.

Transfer Reel-to-Reel Audio 5***** Recommended

Open reel tapes can be recorded at different speeds and obviously need to be played back at that same speed. Tape recording speed is expressed in inches per second, abbreviated to ips. In general, the faster the speed, the better the reproduction quality. You’ll typically come across four or five main speeds. 3¾ ips and 7​½ ips were the speeds used for the majority of consumer market releases of commercial recordings.

Tape Tracks and Channels
Half Track Stereo -  Broadcast standard .There are two channels recording simultaneously in a single direction. There is no Side"B" offering the best sound quality. As tapes age, the audio is far less affected by oxide dropouts.
Quarter Track Stereo - This format uses a quarter of the tape for each track in order to record on both "sides" of the tape. The tracks in use are staggered, effectively doubling the amount of recording time.   
Four Track - This allows four tracks to be recorded simultaneously, utilizing all of the tape in a single direction. There is no Side "B". The advantage of this layout was that four separate recordings could be made independently.
To enable SMPTE time codes, tracks 1 and 2 were assigned to left and right channels of audio, and track 4 was assigned to the Time Code. Track three was used as a guard to protect tracks 1 and 2 from the harsh distinctive time code sound on track 4.

A quarter-track reel-to-reel, also known as four-track 2-channel stereo, is a tape system, which divides the tape into four logical tracks. The tape recorder usually has a stereo head, which plays and records on two of the tracks simultaneously. In order to use the other two tracks, you need to flip the tape over. Hence, reel-to-reel tapes can also have "Side A" and "Side B", similar to compact cassettes. The obvious advantage is that it doubles the running length of the tape, which is more economical.
