Abstract
Official abstract text for this publication.
Data blocks to be stored on a disk-based data storage device (e.g., a hard disk drive, etc.) are coded together to form a plurality of linearly independent network coded blocks. The network coded blocks are then stored on the data storage device. Coded seeking may then be used to retrieve the original data blocks from the data storage device in a time-efficient manner. A read request may be sent to the data storage device requesting an innovative coded packet associated with the original data blocks. In response to the read request, the data storage device may read an innovative coded packet from the disk that is closest to current position of a read element of the device.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for use in retrieving data from a disk-based data storage device having multiple network coded blocks stored therein that are associated with a plurality of native data blocks, the method comprising: receiving a read request requesting retrieval of an innovative coded block associated with the plurality of native data blocks; identifying, in response to the read request, an innovative coded block stored in the disk-based data storage device that i…
