Abstract

Introduced is a new pulse-code modulation (PCM) tape recorder for professional applications. It is capable of 8-channel recording and reproduction. This system is an improved version of the system which was described in the JAES published in September, 1973 (Vol. 21, No. 7). Both systems are compatible, and a four-head, low-band video tape recorder is used as the mechanical part of the recording system. The new system features an emphasis circuit and 14-bit A/D and D/A conversions to improve the dynamic range of the system, as well as a selection circuit for the digital data for high quality duplicating and synchronized recording with two video tape recorders and a PCM converter. Engineering quality considerations and performance data are described.
