Title: Pcm magnetic recording and reproducing device
Inventor: YAMAZAKI SHUSUKE
IPC: G11B27/28
Filed: 1987-05-19
Abstract: PURPOSE:To automatically record program number information in the sub-code area of a magnetic tape, by recording the information in accordance with the time elapsed after recording or reproduction is started and the time information stored in a storage device. CONSTITUTION:A program number (PNO) and its playing time (PRE-T) are successively inputted through operation buttons 1, stored in a RAM 2, and displayed in a displaying section 3. These input are written in the sub-code area 16 of a tape through the magnetic head 12 of a rotary drum 13 at the time of recording. When a playing time (P-T) coincides with the inputted playing time (PRE-T) at the time of playing, the PNO is increased by '1' and the P-T is reset. Then the PRE-T is replaced with the PRE-T of the next PNO stored in the RAM 2. These operations are successively repeated. Since the location of the sound area 17 of the tape 14 is different from that of the sub- code area 16, rewriting can be performed during the recording and reproducing periods. Therefore, program information can be recorded automatically.
