Abstract
A technique includes in a data storage device, sensing a plurality of data streams from a track of storage media as the media moves in a given direction using a plurality of read elements such that at least one of the read elements is redundant. The technique includes combining the data streams to generate a data stream indicating data read from the track.
Claims15
A method comprising:
- in a data storage device, sensing a plurality of data streams from a track of tape storage media as the media moves in a given direction using a plurality of read elements;
- and
- combining the data streams to generate a data stream indicating data read from the track, wherein combining the data streams comprises selecting portions from the data streams containing valid data and combining the selected portions to generate the data stream indicating data read from the track.
(canceled)
A data storage device, comprising:
- a plurality of read elements arranged to read data from a track of magnetic media shared in common as the media moves in a given direction to generate a plurality of read data streams;
- and
- a read path to selectively combine the read data streams to provide a composite read data stream indicative of the data read from the track, read path to selectively combine the read data streams by selecting portions from the read data streams containing valid data and combining the selected portions to provide the composite read data stream.
(canceled)
An article comprising a non-transitory computer readable storage medium to store instructions that when executed by a computer cause the computer to:
- in a data storage device, sense a plurality of data streams from a track of tape storage media as the media moves in a given direction using a plurality of read element
- select portions from the data streams containing valid data;
- and
- combine the selected portions to generate a data stream indicating data read from the track.
