IPC: G11B5/09
Filed: 1981-04-07
Abstract: PURPOSE:To rationalize the processing for errors, by turning on and off the current of an erasing head, which is provided in the lower stream of a write and read head, at the time when the leading edge and the trailing edge of a record, where an error is detected, reach the erasing head. CONSTITUTION:Data DA, DB, and DC are recorded successively on one track of an endless tape 11 by a recorder 3a and are monitored by a monitor 3b. If an error occurs in data DC, a count value T2 corresponding to the time required for the arrival of a point t2 of the tape at a point t3 is loaded to a start counter, and a count value T3 corresponding to the time required for the arrival of a point t1 of the tape at the point t3 is loaded to a stop counter. Loaded count values are counted down by clocks (a); and when the count value of the start counter becomes 0, a current is flowed to an erasing head 20; and when the count value of the stop counter becomes 0, this current is turned off. Thus, an error signal DC is erased immediately to make rewriting possible, and the processing for errors is rationalized.
