Magnetic tape apparatus with a reading head for reading main information, and auxiliary information from two different regions.

摘要

Main signals such as music and the like are read out by heads (DH2-DH9). Simultaneously, auxiliary signals are read out from two sectors on a magnetic tape recorded in opposite directions by heads (DH1,DH10). These signals are provided as serial signals from a multiplexer (8) and digitalized by an A/D converter (10). The digitalized signals are separated into main signals and auxiliary signals by a signal processing unit (12). A microcomputer (17) carries out procedures for high speed search based on to the auxiliary signals, whereby the operation of a mechanism unit (20) is controlled via a mechanism controller (21). <IMAGE>
