Abstract

PURPOSE: To simply ensure the retrieval of desired position of magnetic tape, by cotrolling tape run through the playback of virtual absolute address via tape at high speed running and of absolute address itself under specified speed.
CONSTITUTION: When the difference between the desired absolute address set to the objective address register 27 and the absolute address reproduced fron the tape 10 is less, the switch 25 is changed over via the differnece detection circuit 26 and the servoamplifier 15 is controlled and tape 10 is at low speed running. Further, servocontrol is made unitl the difference output of the circuit 26 is zero to retrieve the set address of tape. If the difference output by the circuit 26 is greater, of tape 10 is in high speed running and the playback head 13 is detached from the tape 10. Further, virtual absolute address is generated from the pulse counter 23 via the roller 14 in contact with the tape 10, it is compared with the set address at the circuit 26, and if the diference is less than the specified value, the tape is changed over to a low speed. Accordignly, the desired position of magnetic tape can simlpy and accurately be retrieved.
