装置。 A read/write function is used in a magnetic tape drive control device that controls the drive of the motor that rotates the magnetic tape when reading/writing data on the magnetic tape.
The apparatus includes an error inspection means for detecting an error, and a control section for controlling the rotational speed of the motor to be slightly changed from the current speed based on a read error detection signal so as to read again the part where the read error has occurred. A magnetic tape drive control device characterized by:
