  • Control head to head spacing using a piezoelectric device
    Patent number: 10783924
    Abstract: Embodiments of the present disclosure generally relate to tape drives used for magnetic recording on tapes, and more specifically to tape heads including servo and data head structures. A tape head includes a plurality of servo head structures and one or more piezoelectric devices. The one or more piezoelectric devices are utilized to control the spacing and dimensions between the plurality of servo head and data head structures. The one or more piezoelectric devices further allow the tape head to receive active feedback from the tape drive, allowing the one or more piezoelectric devices to correct any errors during operation.
