ABSTRACT:
In conventional magnetic disk drives where stream data are treated, seek operations are performed at unnecessarily high speeds. This put the magnetic disk drives at a disadvantage in suppressing noise, reducing power consumption, and lowering the costs of actuator components. In one embodiment of the invention, a magnetic disk drive comprises a magnetic disk medium; a magnetic head; a head actuator to move the magnetic head relative to the magnetic disk medium; and a controller configured to control the head actuator to move the magnetic head to record data to and reproduce data from the magnetic disk medium. The controller is configured to control the magnetic head to record stream data on the magnetic disk medium in such a manner that the stream data is recognizable as stream data. The controller is configured to detect a situation in which two or more stream data are to be recorded or reproduced concurrently so as to set a slower seek operation mode.
