摘要： An apparatus for correcting read errors in a disk drive is disclosed. In one embodiment, the apparatus includes circuitry for determining that an undesired distortion exists in a data signal read from a surface of a data storage disk; circuitry for finding an approximate starting location of said distortion within said data signal; and, circuitry for correcting errors in said data signal caused by said undesired distortion using said approximate starting location of said distortion. A method for correcting read errors in a disk drive is also disclosed. In one embodiment, the method includes the steps of (1) providing an error correction code (ECC) that is capable of locating and correcting errors in a data signal; (2) determining that a data signal read from a surface of a data storage disk includes a distortion; (3) finding an approximate starting location of said distortion within said data signal; and, (4) performing error correction procedures on said data signal, based on said ECC, using said approximate starting location of said distortion

摘要： The disclosure is related to systems and methods of concurrent actions for data storage. A controller may be configured to initialize a first data storage medium and a second data storage medium. The controller may receive a command when the first data storage medium is initialized but before the second data storage medium is initialized. The controller may service the command when the command utilizes the first data storage medium and the initialization for the second data storage medium is not complete. A controller may also be configured to send an indicator to a host that the system is ready to receive commands when a first data storage device is initialized, but a second data storage device is still in an initialization process.

摘要： A trace device for monitoring and storing trace data of a device under test (DUT) is provided. The trace device is coupled in situ with the DUT when the DUT is in its operating environment (e.g., when the DUT is located within a rack, housing, or enclosure including the DUT). The trace device comprises a trace data buffer for storing trace data received from the DUT during operation.

摘要： An off-track error recovery method and apparatus for a disk drive are disclosed herein. Off-track errors are either due to vibration of the disk drive or due to defective servo data stored on a disk surface of the disk drive. In order to tailor error recovery operations associated with each of the two types of off-track errors, the present invention distinguishes between the two types of errors, when possible. Accordingly, the overall time for performing off-track error recovery operations is reduced and/or off-track error recovery operations are made more efficient.

摘要： An adaptive error recovery routine allows for the recovery from errors in read data of a disk drive. In one embodiment, a disk drive is provided which has an error memory having error memory elements used to record an error type and recovery step for each error recovered from the disk drive. If another error is detected that is of the same type and which is in a location close to a recorded error, the error recovery step used for the previous error is performed for the new error. If the previous error recovery step is not successful, the disk drive performs error recovery using an existing error recovery table, and omits the previous error recovery step.
