Abstract
Record-based backward skipping is provided for accessing logical records contained within physical blocks of data of a storage medium. A computing unit coupled to the storage medium reads a current block of data from the storage medium and determines a number of logical records within the current block, as well as the location of each logical record. The number of logical records is then employed to determine whether the desired logical record is within the current block, and if so, a pointer is provided to the desired logical record for skipping back to that record. If the desired logical record is not within the current block, then a previous block is read from the storage medium and the process is repeated to determine whether the desired logical record is within the new block.
