HIGH-DENSITY PATTERN DETECTOR FOR HYBRID SERVO PATTERNS

In one embodiment, a tape drive includes a controller including a processor and logic integrated with and/or executable by the processor. The logic is configured to obtain at least two periodic waveform components of a high density (HD) servo signal read by a servo reader from a HD pattern written on a servo band of a magnetic tape medium. The logic is also configured to filter the HD servo signal using a number of digital filters that are configurable to detect waveform components simultaneously read from the magnetic tape medium, each digital filter being configured to match waveform component parameters and tape velocity. Moreover, the logic is configured to compute a position error signal (PES) based on the filtering of the HD servo signal comprising the waveform components.
