摘要： A storage device capable of avoiding write fault error or read error occurring immediately after switching from power save mode or migration mode to ordinary mode. By carrying out a dummy write/dummy read command when switching from power save mode for reducing electric power consumption or migration mode for reducing the time for which the electric current flows in magnetic heads, normal write command/read command is executed in a condition in which the magnetic heads are placed completely in on-track condition.

摘要： A plurality of recording media combined integrally having a plurality of recording surfaces; and a plurality sets of reading heads and writing heads, combined integrally, provided for the respective ones of the plurality of recording surfaces, are provided. Upon writing data on each recording medium with the writing head provided therefor, a writing position is controlled as a result of positioning information previously provided on the recording media including the recording medium other than the each recording medium being read with the reading heads provided therefor.

摘要： A preamplifier receives a servo gate signal indicating whether magnetic information read out from a disk by a head is servo data for positioning-use or user data stored in a user area available for reading and writing of given data. In the preamplifier, a servo data gain and a user data gain are set in advance. Based on a received servo gate signal, the preamplifier changes the gain depending on whether the head outputs the servo data or the user data.

摘要： A control unit adjusts spacing between a head with a heater and a storage medium of a storage unit by controlling power of the heater. The control unit measures first values of touchdown heater power at a first temperature set as temperature condition. And the control unit estimates second values of the touchdown heater power at a temperature other than the first temperature set on the measurement of the first values, on basis of a conversion equation. And the control unit determines heater power setting values to adjust the spacing between the head and the storage medium, for each of the sub-areas, on the basis of the first values and the second values.

摘要： A guarantee processing method guarantees the data of an adjacent track in the case of a write fault when there is a possibility of an off track write. Even if a write fault is detected or an offset read retry is successful, a rewrite for guaranteeing an adjacent track is not executed immediately. The possibility of an off track write is judged by the movement of the head, and only the sector which is difficult to read due to the off track write is rewritten.
