Half-track tape recorders are a type of recording device used to store audio recordings on magnetic tapes. The name derives from the fact that the tape passes the recording and playback heads at a rate of one-half the speed of full-track machines, thus allowing twice the amount of audio material to be recorded on a given length of tape.

Half-track tape recorders were used mainly in studios and radio production and required some skill to be able to use them properly. The sound quality of these machines was superior to that of full-track machines, and they allowed for more precise editing.

Half-track tape recorders could be used with one, two, or four tracks. With one or two tracks they could record in mono or stereo. With four tracks they could record up to four channels of audio. For example, if two channels of vocals and two channels of music were recorded, the four channels could all be recorded on one strip of tape, rather than having to record the vocals and music separately.

Once the audio had been recorded, it could be edited and mixed down to a single track or multiple tracks depending on the needs of the user. This process allowed for a great deal of control over the final product, and was used by engineers and producers to create the records we hear today.

Half-track tape recorders are no longer used, as digital recording and production techniques have become the norm. While digital recording does offer advantages in terms of cost and convenience, many music lovers still long for the sound of recordings made on half-track tape recorders.
