  • Method and apparatus for optimizing skip mask operations in a disc drive
    Patent number: 6868477
    Abstract: A skip mask mechanism is implemented in a disc drive in order to increase performance by minimizing the number of necessary disc rotations required while executing a set of pseudo-sequential commands. The drive includes an interface between the host computer and the drive, a read/write channel between the interface and the transducer/head, a formatter between the interface and the read/write channel for timing when data is transferred between the interface and the read/write channel, and a skip mask mechanism interposed between a target calculator and the formatter that provides a masked input to the formatter for controlling passage of data between the interface and the read/write channel.
