Abstract

PURPOSE:To detect the accurate position of an inter-record gap by temporarily switching a write magnetic head to a read magnetic head before the start of write to perform such control that the inter-record gap has a prescribed length. CONSTITUTION:When write of a record 41 on a magnetic ape 40 by a write head 48 is terminated, the tape 40 is returned to a position H1 and is topped. When the next record will be written, the speed of the head 48 reaches a certain sped after rising in the forward direction, and a terminal part P1 of the record 41 is detected. The head 48 is switched to a read head 47 then to confirm detection of a preceding record gap IRG 44. When the IRG 44 is confirmed, the head is switched back to the write head 48 to overwrite the record on a preceding IBG from a point P2. When the whole of the IBG is completed, data is written in a record 42. Since data is written after confirmation of the preceding IRG, an accurate IRG is obtained.
