Abstract: Apparatus and method for managing a media cache through the monitoring of operational vibration of a data storage device. In some embodiments, a non-volatile media cache of the data storage device is partitioned into at least first and second zones having different data recording characteristics. Input data are received for storage in a non-volatile main memory of the data storage device. An amount of operational vibration associated with the data storage device is measured. The input data are stored in a selected one of the first or second zones of the media cache prior to transfer to the main memory responsive to a comparison of the measured amount of operational vibration to a predetermined operational vibration threshold.

Abstract: A method and system for managing the transfer of data into and out of a buffer in a disc drive is disclosed. The operation of the vectored buffer management (VBM) system is administered by a software-based control module. The control module creates and maintains a buffer table by dividing the buffer table into buffer sectors. The buffer sectors are further arranged into buffer segments, or circularly linked lists upon which the buffer table is partitioned. The control module effectuates the transfer by implementing an application module across the buffer table. Once the application module is arbitrarily positioned at an index sector by the control module, data transfer is accomplished when the application module walks through a particular buffer segment identified by the index sector. Specific control of the application module across a buffer segment is administered through host and disc address pointers, which are coupled to host and disc next pointers, respectively.
