Latest Patents

Hasegawa's latest patents include a "Magnetic Disk Device and Method" and a "Data Recording Apparatus and Data Recording Method." In the first patent, he describes a method where, upon failure in detecting a servo mark from servo data during a write operation, the controller of the magnetic disk device halts the write process. The controller then demodulates the servo data from a short servo sector preceding the normal servo sector and resumes writing from the data area immediately after the normal sector. The second patent outlines a data recording apparatus that features a disk, a read/write head, and a control circuit. This apparatus is designed to read first data on the disk in a specific format and write second data, which is generated by compressing part of the first data, in a different format based on the size of the second data.
