Abstract
PURPOSE:To speedily retrieve and rewrite an arbitrary place necessary for the storage device of a computer by composing a block of plural tracks and using at least one track as a gap between the blocks. CONSTITUTION:The block is composed of plural blocks, and at least one track is used not as valid data but as the gap in the last one track of the block or before and after the block, consequently, between the blocks. By using such a tape, a system control circuit 24 instructs a driving control circuit 18 on an EOI search to indicate that the valid data block does not exist thereafter. Then, the circuit 18 makes a servo circuit 14 into a high-speed search mode, it drives a motor 10, an output from a rotating head is sent to a signal processing circuit 16 in being made into a waveform-shaped digital signal, and an EOI block is detected through a subcode control circuit. Thus, the arbitrary place necessary for the storage device of the computer can be speedily retrieved and rewritten.
