Zusammenfassung:	Techniques for performing precise tracking in optical tapes are provided. The techniques include providing and using a servo pattern on an optical tape. The servo pattern includes a first set of parallel physical grooves slanted in a first direction across a width of the optical tape and a second set of parallel physical grooves slanted in a second direction that is different from the first direction across the width of the optical tape. Subsets of the first set of parallel physical grooves alternate with subsets of the second set of parallel physical grooves along a length of the optical tape. Two subsets of the first set of parallel physical grooves separated by one subset of the second set of parallel physical grooves form a servo frame in the optical tape.
