APPARATUS, SYSTEM, AND METHOD FOR TIMING BASED SERVO TAPE FORMATING
First Claim
1. An apparatus to format a timing-based servo pattern, the apparatus comprising:
- a first write head comprising at least four write elements configured to each concurrently write a stripe to a magnetic tape, wherein in response to at least one first write signal a first and third write element write a base number of stripes to a plurality of first stripe patterns, a second and fourth write element write the base number of stripes to a plurality of second stripe patterns; and
a second write head comprising at least two write elements configured to each concurrently write a stripe to the magnetic tape, wherein in response to at least one second write signal a fifth write element writes an incremental number of stripes to a specified first stripe pattern of the plurality of stripe patterns to form a first incremental stripe pattern and a sixth write element writes the incremental number of stripes to a specified second stripe pattern of the plurality of second stripe patterns to form a second incremental stripe pattern.

Abstract
An apparatus, system, and method are disclosed for formatting a timing-based servo pattern on a magnetic tape. A first write head concurrently writes a base number of stripes to a plurality of first stripe patterns with a first and third element and writes the base number of stripes to a plurality of second stripe patterns with a second and fourth element of a first write head in response to at least one first write signal. A second write head concurrently writes an incremental number of stripes to a specified first stripe pattern to form a first incremental stripe pattern with a fifth write element and writes the incremental number of stripes to a specified second stripe pattern to form a second incremental stripe pattern with a sixth write element.
