Digital recording is a technique for preserving audio signals and video or visual images as a series of pulses that can be stored on magnetic tapes, optical discs (compact discs), or computer diskettes. These pulses are stored in the form of a series of binary digits (that is, zeros and ones). To make the recording, an analog-to-digital converter transforms the sound signal or visual image into digital information (a complex series of zeros and ones) that is recorded on high-speed magnetic tape or on disc or diskette. The system that plays back or reads out the sound or image translates the binary code back into analog (line like) signals using a digital-to-analog converter. Tape players, compact disc players, video disc players, and CD-ROM (Compact Disc-Read-Only Memory) players in home computers are examples of digital-to-analog converters used to play back audio and video codes in our homes.

Analog recordings were the only ones made until the digital revolution of the 1970s, and used a variety of methods that are now considered outdated like long-playing (LP) records, eight-track tapes (on either metal or magnetic tape), and home movies. In the history of sound and video recording from early in the twentieth century until the 1970s, the analog system seemed ideally suited to recording…
Digital recording itself produces truer audio and video, and the systems developed for playing them also help eliminate interference. The most familiar audio system, the compact disc, uses a laser beam player to read the digital information coded on the disc. Digital audio tape (DAT) became available in the late 1980s. It uses magnetic tape and a specialized DAT recorder with a microprocessor to c…
Recording, particularly of music and video images, consumes massive amounts of digital memory. High-density discs are ideal for these types of recording. Direct digital recordings can play back recorded or modulated sound. Tape recording, though convenient and easy, could not store digital data until the development of the DAT tape. Carrier signals in digital recording are always pulse waves that …
Recordable and erasable CDs are giving the compact disc greater versatility. Compact disc recorders allow the user to record audio from various sources on CDs. The recorders require attentive use because the recording procedure depends on the type, quality, and input device of the source material. If the source is a CD that can be played on a machine with digital optical output, it can be connecte…
