<p>PURPOSE:To exactly record a program number on its original position in a frame unit, by increasing and recording the program number at every start signal. CONSTITUTION:A program start signal 1 in a subcode area is detected by a system controller 26 through a subcode microcomputer 25, while feeding a magnetic tape 14 at high speed, and an address signal in a PCM area at that time is read out, and is stored in the controller 26. The frame address, after the being added, is stored in the register of the controller 26 as the program number. Since a similar operation is performed repeatedly at every program start, and the generation of the same program number in every block can be prevented, and the position of the tape can be detected exactly, it is possible to record the program number exactly in the frame unit.</p> |
