ABSTRACT:
The present invention relates to a recording speed determining method of a disk device. The present method, when data record is requested from a host through an interface, a disk device can receive size information about data to be recorded and/or the present time from the host, and determine a recording speed of a disk to be suitable for the received size information and/or for a time zone where the device is located. The disk device can determine such data size and time zone information internally. Thus, it is possible to reduce a noise that is caused from disk rotation if the size of data to be recorded is small or when a noise is felt relatively big. Further, it is possible to determine a data recording speed in accordance with a data size.
