Altitude insensitive air bearing using pitch compensation for data
storage application
摘要:
An air bearing slider for supporting a magnetic read/write head on a moving disk includes at least one front force carrying pad located in front of a suspension pivot point of an air bearing slider, at least one rear force-carrying pad located behind the suspension pivot point of the air bearing slider, and a trailing-edge pad having a magnetic read/write head embedded in a rear portion of the trailing-edge pad. Each front force-carrying pad carries a front air bearing force that is generated by a relative motion between a surface of the disk and the slider when the surface of the disk has a predetermined disk velocity with respect to the slider. Each rear force-carrying pad carries a rear air bearing force that is generated by the relative motion between the surface of the disk and the slider. The trailing edge pad carries substantially no air bearing force. According to the invention, as an atmospheric pressure associated with the air bearing slider decreases, a flying height associated with each front force-carrying pad and each rear force-carrying pad decreases so that a pitch angle of the air bearing slider decreases and a flying height associated with the trailing-edge pad at the magnetic read/write head changes by less than 5 nm at a predetermined disk velocity.
