Abstract

PURPOSE: To make a simple and sure data processing possible by recording index and file name signals, which are modulated by low and high frequency signals, on a cassette tape together with data signals.
CONSTITUTION: Index signals A modulated by a prescribed low frequency signal, burst-form file name signals B modulated by a prescribed high frequency signal, and recording signals constituted by data signals C, etc., are supplied from a CPU and are recorded on a cassette tape. When this cassette tape is reproduced in a fast-feeding mode and is processed by a prescribed BPF, the tape is searched by reproducing index signals A'. Next, when the tape is caused to run in a normal speed, reproducing full name signals A' are read out, and reproducing data signals C' following signals A' which agree with the file name indicated by the CPU are read out.
