Abstract
PURPOSE: To accurately detect the recording types of magnetic tapes by providing a means of sequentially performing collating with the patterns expected for parallel signals.
CONSTITUTION: Recording density indicator signal (ID burst) parts 2 are recorded across plural tracks. If it is assumed that the read signal of the ID burst coincide with the pattern having been set in gate 14, there is an output signal only in the gate circuit 14 and the signal is sent out to output terminal 12 only when the signal is applied from a control circuit 19 to an AND circuit 17. Thereby, the recording type corresponding to the input combination patterns of the AND circuit 14 is identified as the recording type of this magnetic tape.
