Disk device

Abstract

Abstract PURPOSE:To prevent an error or the destruction of data due to oscillation or shock occurring by prohibiting recording when the aberration of a head i.e. off-track is detected by an off-track detection circuit. CONSTITUTION:The off-track detection circuit 16 to detect whether or not the head 5 in scanning is deviated by a prescribed quantity is provided, and the recording with the head 5 is prohibited replying to a signal representing the deviation exceeding the prescribed quantity obtained from the off-track detection circuit 16. Thereby, since write is prohibited when the head 5 is remarkably deviated from a prescribed track 2 due to the oscillation or the shock, the erroneous destruction of the data on an adjacent track can be sent out, and a device can be used at a state where the oscillation or the shock may be applied on the device.
