Latest Patents

One of Itou's latest patents is a disk device that includes a function to confirm that a selected head is appropriate for a disk surface. This invention aims to prevent data loss caused by incorrect head selection, thereby enhancing the reliability of information recording and reproduction. The device utilizes a SAM pattern in the servo information region, which is altered for each head and recorded. By reading this pattern, the device can determine which head accesses the disk surface and perform an error check against the designated head.

Another significant patent is a method for compensating the timing to start data recording, along with a magnetic disk device that employs this method. This innovation addresses head-to-head variations in the gap distance between write and read heads. It measures the gap distance for each head by writing and reading a unique pattern, allowing for precise timing adjustments in data writing. This ensures that data is written at the desired physical position, improving formatting efficiency.
