Latest Patents

One of his latest patents is an error correction method and apparatus for a magnetic disk storage device. This invention employs an on-the-fly, multiple burst error correction system that detects and corrects errors in data sectors stored on a magnetic disk. The system enhances the probability of successful byte synchronization to the data field, even in the presence of noise, such as defects in the storage medium. Additionally, a sync mark may be embedded within the data field to facilitate byte resynchronization when synchronization is lost.

Another notable patent is an error correction system included in a utilization device. This system operates on a plurality of sectors stored in a data buffer for performing write-from-host and read-from-device operations. It features overlapping and asynchronous operational steps, including sector transfer into the buffer, sector correction, and sector transfer out of the buffer. The system comprises several subsystems supervised by a correction controller, which includes CRC generation and checking, LBA, ECC/Syndrome Generator, header, correction, and correction checker subsystems.
