摘要： A plurality of retry tables is used for adaptive and flexible error correction during a read/write operation within a disk drive. The plurality of retry tables is stored in a data storage unit, and one of the retry tables is selected to be used for the error correction. In addition, firmware is not modified for using any of the plurality of retry tables during the error correction. One of the retry tables becomes eventually selected as being optimum for the error correction depending on an application, operating conditions, and head/mechanical characteristics of the disk drive.
摘要翻译：在磁盘驱动器内的读/写操作期间，多个重试表用于自适应和灵活的纠错。多个重试表存储在数据存储单元中，并且其中一个重试表被选择用于纠错。此外，在错误校正期间，固件不被修改用于使用多个重试表中的任何一个。根据磁盘驱动器的应用，操作条件和磁头/机械特性，其中一个重试表最终被选择为对于纠错的最佳选择。

摘要： A method and apparatus to control an operating clock frequency of a hard disk drive. The method includes analyzing a command workload, and changing the operating clock frequency of the hard disk drive based on an analysis result. Alternatively, the method includes measuring a time taken to receive a predetermined number of write/read commands and controlling the operating clock frequency of the hard disk drive based on a result of a comparison of the measured time with at least one reference value. An operating clock frequency control block included in the hard disk drive executes the method.

摘要： For performing a retry in a data storage device, a spin jitter value corresponding to a desired sector of a disc is determined. A read timing is adjusted according to the spin jitter value of the desired sector. A retry of a data read is performed for the desired sector with the adjusted read timing. Thus, the present invention accounts for eccentricity of the disc as indicated by the spin jitter value during retry of the data read operation.
