Title: Data recording and reproducing device
Inventor: NAKAI JIYUN
IPC: G11B20/10
Filed: 1983-06-17
Abstract: PURPOSE:To eliminate the mutual interference between the 1st and 2nd auxiliary data and to facilitate the extraction and separation of these data, by selecting a bit frequency so as to separate sufficiently the frequency bands of both auxiliary data with each other then recording these data after applying frequency multiplexing. CONSTITUTION:The 1st and 2nd auxiliary signals S-AMS and S-SUB which must be reproduced in the high speed and fixed speed modes are supplied to a signal converting circuit 30 via terminals 7 and 8 respectively. The circuit 30 converts both signals S-AMS and S-SUB into the prescribed digital codes respectively and selects each bit frequency so as to separate sufficiently the frequencies of both signals with each other. Then these signals are applied with frequency multiplexing to be outputted. These signal outputs are recorded to a signal auxiliary track of a recording tape 5 with relationship to a main digital code signal. While a reproduction system reverses the signal operation of a record system via a signal adversely converting circuit 50.
