Abstract: PURPOSE:To prevent an error from being generated in detection results even when an azimuth component is generated by selectively switching the function of one write gap to a write gap function and a read gap function and not only writing a signal but reading the written signal with one gap to detect the tape edge. CONSTITUTION:A tape 4 is run, and a magnetic head 1 is moved in the breadthwise direction of the tape 4 from a preliminarily determined initial position to record a signal 8 on the tape up to the edge of the tape. Thereafter, the tape 4 is rewound to the initial position, and the magnetic head 1 is moved back to the position where the signal 8 is recorded. Next, a write gap W is connected to a reading circuit and is caused to function as the read gap, and the tape 4 is run, and the magnetic head 1 reads the signal 8 recorded on the tape while following up the signal. The read signal 8 is compared with a reference value to detect the edge of the tape 4. Thus, the tape edge is detected based on the distinct reference even when the azimuth is deviated.
