Abstract
An optical data storage tape includes more than one segment, with each segment divided into multiple zones, which include multiple data tracks. The layout of the logical zones in one segment is in a different order than those of another segment. In an example, the tape includes at least N physical segments, at least M physical zones in each segment, at least M logical zones assigned to the M physical zones, and wherein logical zones of adjacent physical segments are in a different order than an adjacent physical segment.
Claims15
An optical data storage tape comprising:
- at least N physical segments;
- at least M physical zones in each segment, wherein the physical zones are sequentially the same in each segment;
- at least M logical zones assigned to the M physical zones;
- and
- wherein a first logical zone of the logical zones in a first physical segment of the physical segments is assigned to a first physical zone of the first physical segment;
- wherein a first logical zone in a second physical segment of the physical segments is not assigned to a first physical zone of the second physical segment.
3 more elements
An optical data storage tape system comprising:
- N optical tape drive units for reading a plurality of logical storage segments;
- an optical tape to be read by the optical tape drive units, the optical tape having a plurality of physical segments that are associated with the logical storage segments, respectively, the physical segments each having M physical zones that are each arranged in a same physical sequence;
- and
- wherein logical zones of adjacent physical segments are in a different order with a first drive unit of the optical tape drive units reading a first logical zone of a first logical segment of the logical storage segments being in a different position than a second drive unit of the optical tape drive units reading a first logical zone of a second logical segment of plurality of logical storage segments.
