摘要： A fixed data region on a storage medium may be allocated with one of a variety of allocation schemes (e.g., a randomly writable allocation scheme, a non-randomly writeable allocation scheme with a first data isolator spacing, a non-randomly writeable allocation scheme with a second data isolator spacing, and a non-randomly writeable allocation scheme with no dynamic isolators). Dynamic sub-region spacing refers at least to the number of data tracks in a data region of a magnetic disc between dynamic isolators and the number of bits in a data region in flash memory between dynamic isolators. The presently disclosed technology adapts isolators on the storage medium to create dynamic sub-regions based on characteristics of the storage medium, characteristics of the data, and/or expected access patterns of data to be written to the storage medium.

摘要： A storage device controller may segregate data units that are typically accessed together to a common storage unit. In one example, a storage device includes a control unit configured to receive a plurality of logical blocks to be stored in the storage device, wherein a first set of addresses comprises logical block addresses (LBAs) of the plurality of logical blocks, and a non-volatile memory configured to store logical blocks in a plurality of storage units, wherein one of the plurality of storage units includes logical blocks corresponding to a second set of addresses. The control unit may determine an intersection of the first set of addresses with the second set of addresses and to store each of the logical blocks having LBAs in the determined intersection of addresses in a common storage unit of the storage device, wherein the common storage unit comprises one of the plurality of storage units.

摘要： Method and apparatus for actively protecting a device from damage due to an impact or other acceleration condition. An active protection system is provided with a sensor which outputs an acceleration signal in relation to an acceleration state of the device. A circuit processes the acceleration signal in relation to a configuration control input indicative of an operational environment in which the device is operated, and a protection mechanism configures the device in relation to the processed acceleration signal. A configuration control module preferably supplies the configuration control input as a user selectable or host input. Preferably, protection mechanism places the device in a protective state to protect against damage due to an imminent impact, such as from a free fall condition. The processing preferably comprises adaptive filtering of the acceleration signal and the application of one or more thresholds to detect said imminent impact.

摘要： Herein is disclosed a method and apparatus for optimizing a disc drive for audio-visual data storage and retrieval by responding to a certain read-time error in a manner that preserves data flow. In response to a read-time error in which a synchronization field associated with a given sector on a disc is undetected, the disc drive responds by transferring a fill pattern of bits or a return status to the host microprocessor so as to indicate the error, and allow the disc drive to continue attempting to seek subsequent synchronization fields. The fill pattern of bits may be chosen so as to minimize the negative impact of processing the unread data by down-stream audio-visual equipment. The aforementioned behavior is a departure from the traditional sequential paradigm of a conventional disc drive. The new behavior preserves data flow, a quality important to audio-visual drives.
