Abstract: PURPOSE: To enhance probability of retry success with a simple circuit constitution, by detecting and storing occurrence of read error to change the driving characteristic of a magnetic tape.  
     CONSTITUTION: Magnetic tape 6 runs due to DC motor 2, which is subjected to feedback control through capstan control circuit 16, and capstan roller 4, and data is readout by read head 18. Each time read error occurrence is detected through read circuit 20 and control circuit 24, retry is performed by circuit 16, and simultaneously, the retry frequency is stored in retry frequency memory control circuit 32; and when this frequency reaches a prescribed value, the control signal outputted from circuit 32 is changed to change the driving characteristic of motor 2 dependent upon circuit 16. Consequently, even if the recording density is not uniform due to slip, etc., of roller 4 at a write time and change dependent upon time elapse exists between the write time and the read time, read is so controlled that the driving characteristic of the magnetic tape may be changed to drive the tape with a gentle side characteristic, thereby improving probability of retry success to enhance reliability of the tape device.
