Latest Patents

Masuyama's latest patents include a disk device and a disk device control method. According to one embodiment, a disk medium rotates in a first rotation state when access is given, and rotates in a second rotation state lower in rotation number than the first rotation state when access is not given. A controller receives, from a host device, a read command for reading first data stored in a first buffer when the disk medium is in the second rotation state. The controller transmits the first data from the first buffer to the host device without causing a shift into the first rotation state, and then shifts the disk medium into the first rotation state after completion of execution of the read command. Another patent describes a storage device, controller, and method. This storage device includes a magnetic disk, a head, and a control unit. The magnetic disk comprises a plurality of physical sectors having a first length. A logical block having a second length shorter than the first length, and a redundant area having a length of the difference between the first length and the second length are assigned for the physical sectors. The head reads the data from the physical sector of the magnetic disk. The control unit controls to change the second length of the logical block while maintaining the first length of the physical sector in response to reception of a change request for changing the second length of the logical block from a host.
