Abstract
PURPOSE: To perform writing and reading out of data to and from desired address regions without reading out the control portions having been written in a tape by writing addresses on the magnetic tape.
CONSTITUTION: Data recording tracks 12 thru 18 and an address track 11 are provided on a magnetic tape 1. The values of the addresses to read out or write data are stored in a register 61 via control circuit 44. On the other hand, the addresses on the magnetic tape are detected from a read head 51 and are read out in a register 62. Both are compared in a comparator 63 and the tape is taken-up or rewound. This is repeated and when the values of the registers 61, 62 coincide, they are sent to a magnetic tape control unit 2 via buffer 54. Hence, the reading and mriting of data from and into desired portions may be performed according to the addresses on the magnetic tape and in addition the taking-up and rewinding of the tape may be controlled.
