Latest Patents

Horiguchi holds a patent for a "Disk drive and method of writing servo write tracks to a disk." This patent describes a system and method that utilizes a head with a read/write offset to write servo write tracks on a rotating disk. One embodiment of his invention employs a write element on the head to write the servo write tracks. A read element is then positioned over these tracks to measure the phase of a specific frequency component of the track shape error. Based on these measurements, a sine wave is selected and applied as a correction signal to the servo system, allowing for the writing of a new servo write track.
