Latest Patents

One of his latest patents is titled "Method for using one of two storage directories only after the other." This invention discloses a system that stores write management information, identifying which sectors have been written and which sectors are available for writing in a magneto-optical disk with write-once-read-many (WORM) capability. The write management information is stored in a separate write management directory on the media, which is typically loaded into the drive controller memory when the media is first loaded into the drive. Whenever the drive receives a write command, it checks the write management directory to determine if the sector has already been written. If the directory indicates that the sector has already been written, the drive returns an error; otherwise, the drive writes the sector and updates the write management directory.

Another notable patent is "Method and apparatus for determining sector status in a data storage." This invention allows writable magneto-optic (MO) data storage media to be defined as read-only. Each sector of the media contains an error recovery section, called the defect management pointer (DMP). In MO media, error recovery information is stored at a common location, so the DMP of each sector is used to indicate the state of the sector—writable or read-only. A special data pattern is used to indicate whether the sector is blank or contains user data. Once the storage state has been changed to the read-only state, the drive will no longer write data into this sector.
