Abstract
Techniques for processing tape storage include determining a current position of a read device to read a data block from a tape storage medium having a plurality of duplicate data areas, receiving a request to read a data block from the tape storage medium, and reading the requested data block from a duplicate data area from among the plurality of duplicate data areas that is nearest the current position of the read device.
Claims20
A tape storage processing apparatus comprising:
- a tape storage interface having a tape read device to read data blocks from a plurality of duplicate data areas on a tape storage medium;
- a host interface to receive a request to read a data block from the tape storage medium;
- and
- a tape storage manager to determine a current position of the read device relative to the plurality of duplicate data areas and to read the requested data block from a duplicate data area from among the plurality of duplicate data areas that is nearest the current position of the read device.
A method of processing tape storage, the method comprising:
- determining a current position of a read device to read a data block from a tape storage medium having a plurality of duplicate data areas;
- receiving a request to read a data block from the tape storage medium;
- and
- reading the requested data block from a duplicate data area from among the plurality of duplicate data areas that is nearest the current position of the read device.
A computer readable medium comprising code that if executed causes a processor to:
- determine a current position of a read device to read a data block from a tape storage medium having a plurality of duplicate data areas;
- receive a request to read a data block from the tape storage medium;
- and
- read the requested data block from a duplicate data area from among the plurality of duplicate data areas that is nearest the current position of the read device.
