Abstract
PURPOSE:To speed and facilitate control and to improve total performance by performing unchangeable accelerating operation during a high-speed run of a tape even when a write or read instruction is supplied, and setting a target when the acceleration ends at an intermediate point between data blocks. CONSTITUTION:In a running processI, a tape is run with prescribed acceleration by a write instruction to place a recording head WH right before a data block D3, and also to obtain a prescribed speed, and accelerating operation is stopped. In a running process II, writing to the data block D3 is carried out and a check is made through the reproduction of a reproducing head RH, thus completing the operation after the reproducing head RH passes the tail end of the D3. After a process III of decelerating and stopping the tape, the tape is fed backward by a high-speed indication instruction at a high speed to a constant distance. in processes IV-VI. In a process VII, the head is stopped at an intermediat point between blocks D3 and D4 by a write instruction in the same wave with the processI, and in a process VIII. Threfore, the control is speeded and faciltated, and total performance is improved.
