Glossary 203 Physical formatting-Also known as "low-level formatting," disk formatting that, in addition to initializing the disk's filing system, divides tracks into sectors. Contrast with logical formatting. REL-An abbreviation for Relative. Contrast with ABS. Rew-An abbreviation for rewind. RTZ-An abbreviation for Return To Zero. A recorder function providing a quick way to locate the zero position. S/PDIF interconnect format-The digital audio interconnect format, developed by Sony and Philips, for transferring digital audio between consumer-type digital audio equipment, such as CD players, consumer DAT decks, and MiniDisc decks. Two channels of digital audio (left & right) are carried in an unbalanced connection, usually a phono or optical connector. Sampling rate - The number of times per second an analog audio signal is sampled (i.e., measured) during A/D conversion. SCMS (Serial Copy Management System)-Pronounced "scums," a protection system intended to prevent illegal copying of music. SCMS allows one-time serial copying of copy-protected material. If the source is not copy protected, it's possible to make any number of digital-to-digital copies of the material. If the source is copy protected, however, it's possible to make a first-generation copy, but further copies cannot be made from the first-generation copy. SCMS is only effective when copying via digital connections. Recordings made via analog connections are not affected. SCSI (Small Computer Systems Interface)-Pronounced "scuzzy." A parallel interface for connecting computers and peripherals, such as hard disk drives, removable disk drives, and scanners. Up to eight devices (including the host computer) can be connected to a single SCSI bus. SCSI ID-An exclusive identity number assigned to each device on the SCSI bus. SCSI terminator-A resistive device, installed at both ends of the SCSI bus, to eliminate transmission errors. Signal-to-noise ratio (S/N)-In an audio system, the difference between the operating signal level and the residual noise floor, expressed as a decibel ratio, and commonly used to measure a system's noise performance. SMPTE/EBU timecode-SMPTE/EBU timecode is the timecode format approved for television by the SMPTE (Society of Motion Pictures and Television Engineers) in the United States and the EBU (European Broadcast Union) in Europe. Tascam TDIF-1 interconnect format-The Tascam Digital InterFace audio interconnect format typically found on Tascam TDIF-1-compatible digital audio equipment. TDIF-1 is a bidirectional, 8-channel format, which uses 25-pin D-sub connectors. TC-An abbreviation for timecode. THD (Total Harmonic Distortion)-The amount of distortion introduced by an audio system relative to the audio signal, expressed as a percentage. Compared to third-harmonic distortion, which is the measure of a single harmonic, total harmonic distortion is the sum of distortions produced at all harmonics. TR-An abbreviation for track. Unity gain-A gain of one. VFD-An abbreviation for vacuum fluorescent display. Video sync-The black burst or color bar component of a composite video signal used as a timecode reference with video editing equipment. D24-Owner's Manual
