Filed: 1988-02-18
Abstract: PURPOSE:To accurately distinguish a head crash from an off track and to detect the head crash by making the title system execute appropriate offset action for every data head and examining the level of a signal waveform under this state. CONSTITUTION:A control means 17 makes a position error detecting means 20 detect the off track quantity and the off track direction of a data head 7 at every time designated by a timing means 18 and records them on an offset table 12. Thereafter, the means 17 makes the system execute the offset action for a servo head 6 using the recorded offset quantity and offset direction during a period up to a next time informed by the means 18. Thus, it is possible to always give the optimum offset quantity to the head 6. Consequently, the off track of the head 7 is always corrected, and the level of the signal waveform of the data read by the head 7 is to be normal all the time when the head crash does not exist. Thus, a head crash detecting means 21 can detect the occurrence of the head crash by the lowering of the level.
