Abstract
The present disclosure is generally related to a tape drive comprising a tape head and a controller coupled to the tape head. The tape head comprises one or more modules, each module comprising a plurality of write heads aligned in a first row, a plurality of read heads aligned in a second row parallel to the first row, and at least four first servo heads aligned in the second row. Two or more first servo heads of the at least four first servo heads are configured to concurrently read first servo data from a first servo track. The controller is configured to concurrently process the first servo data, to compute the position of the tape head based on a known spacing between the at least two servo heads, and to dynamically adjust a position of the tape head based on the processed first servo data.
