Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

G06F 1300

US Classification:

711112, 710 52, 710 56

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.

International Classification:

G11B 5/54
G11B 21/12

US Classification:

360 75

Abstract:

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.

US Classification:

36518503, 36518517, 36518514, 36518505, 36518906

Abstract:

A method includes programming a non-volatile memory. The memory includes a plurality of cells, wherein each cell is configured to store a plurality of values, wherein each of value is represented by N digits where N is an integer greater than 1, wherein each of the plurality of cells is further configured to store electric charge representing a plurality of voltage levels, and wherein each of the plurality of voltage levels represents one of the plurality of values. Programming comprises providing the plurality of voltage levels into a first group of voltage levels and a second group of voltage levels in one of the plurality of cells, wherein a highest voltage level of the first group is less than or substantially equal to a lowest voltage level of the second group, and storing, in the first group of voltage levels, electric charge representing a value comprising, at most, N-1 digits.

International Classification:

G06F 11/00

US Classification:

714 16, 714 61

Abstract:

Methods and systems are disclosed to generate a data map for a data storage device. A data map may be generated by scanning, during a power-on initialization process, data units of data stored on a data storage medium of a data storage device. The scanning may start from a selected data unit and proceed through the data units in an order opposite to a write order to identify a first data unit that is not fully erased. Also. an error recovery status of the first data unit may be determined based on an error correction code. A likely erased status of the first data unit may be assigned when the determined error recovery status is unrecoverable.

US Classification:

711170, 711154, 711E12001, 718102

Abstract:

The present disclosure provides a method in a data storage system. The method includes defining a plurality of jobs for a command received from a host. Each of the plurality of jobs is associated with one or more of a plurality of data storage resources of the data storage system. The plurality of jobs have a defined order that is a function of addresses of data in the plurality of data storage resources. The method also includes issuing the plurality of jobs to the associated data storage resources and receiving information from the data storage resources for the plurality of jobs. The information is received by a controller of the data storage system for the jobs in an order that is different than the defined order. The method includes transmitting the received information to the host for the plurality of jobs in the defined order.
