Claims10
A data storage system comprising:
- an optical linear tape including an embossing layer and a phase change recording layer on the embossing layer, the embossing layer including a plurality of land and groove defining a plurality of tracks, each of the tracks having edges exhibiting portions of two cycle wobble having non-coherent phase indicative of index fields for address fields of the track on the tape.
A data storage system comprising:
- an optical media having a plurality of grooves formed therein, each of the grooves at least partially defining a track having edges exhibiting fields of two cycle wobble defining non-coherent phase modulated patterns indicative of index fields for address fields of the track on the media.
A linear tape comprising:
- an embossing layer forming a plurality of tracks, each of the tracks having edges exhibiting fields of two cycle wobble defining non-coherent phase modulated patterns indicative of index fields for address fields of the track on the media;
- and
- a recording layer adjacent to the embossing layer.
