使用している。[Conventional technology] In order to improve the average data transfer speed between the host computer and the disk drive, conventional disk drive devices are equipped with buffer memory of several tens to hundreds of kilobytes in the disk drive device itself, and a portion of the buffer memory is As stated in claim b), there is a cache memory system that temporarily stores frequently used data based on a certain algorithm, and data that is likely to be read next is stored in advance from the media. It is used as a data management function such as look-ahead memory for reading and holding.

メディアである。[Problem to be Solved by the Invention] However, in such a writing speed improvement means, the recording data sent from the host computer to the disk drive device is not immediately written to the medium, but is held in the buffer memory through the data management circuit. For,
There may be a time delay before the recorded data is actually written to the media. If an abnormality occurs in the main power supply such as a power outage during that time, the data held in the buffer memory will be lost, and the write operation will be interrupted [Example] [Means for Solving the Problem] Disk drive of the present invention are: a) a buffer memory that temporarily holds data read from a medium or data written to the medium; and b) the data O7 determined by a certain algorithm is a medium.

[Effects of the Invention] Recorded data temporarily held in the buffer memory by a write command from the host computer can be maintained by the compensation provided inside the drive device even in the event of a power failure.
