Latest Patents

Takanori Sumi holds a patent for a disk controller, disk drive device, and disk control method. According to one embodiment, the disk controller includes a receiver, a read-modify-write controller, and a wait controller. The receiver is designed to receive data in units of predetermined data length. The read-modify-write controller performs a read-modify-write operation when the receiver receives the data, allowing it to write the data to a sector on a disk medium, the rotation of which is controlled. Notably, the sector is longer than the predetermined data length. The wait controller delays the start of the read-modify-write operation by the read-modify-write controller for a duration that corresponds to the time it takes for the disk medium to rotate once, which is substantially the same as the time required to control the read-modify-write operation.
