Abstract
A disk device having access to a disk in different writing modes includes a host PC. The host PC sends a command including a data transfer rate to a controller (disk drive). When the command designating the data transfer rate is received, the writing mode employed for writing data to a disk is automatically switched. The host PC already has the transfer rate to be sent. It is unnecessary to newly prepare a special command to notify the controller in order for switching between the writing modes. Therefore, versatility will not be impaired.
