More Information
Summary:The present disclosure generally relates to a tape drive comprising a tape head. The tape head comprises one or more data heads and one or more servo heads. Each servo head comprises a first shield, a first lead, a magnetoresistive sensor, a second lead, a second shield, and side shields. The magnetoresistive sensor is recessed from a media facing surface (MFS). The first lead is recessed from the MFS while the second lead and side shields are disposed at the MFS. A power supply is configured to apply a first electrical potential to the first and second shields, the side shields, and the second lead, and a second electrical potential to the first lead. The electrical design of each servo head is configured such that only one electric potential is exposed at the MFS, eliminating the possibility that a scratch will short the sensor.
