Abstract:
1. A method of operating a head stack assembly for at least one member of a parking operation group consisting of a take-off process of at least one slider from a rotating disk surface of a Contact Start-Stop (CSS) hard disk drive and a touchdown process of said slider to the disk surface of the CSS hard disk drive, comprising the step: receiving a temperature reading from a temperature sensor, a pressure reading from an air pressure sensor and a humidity reading from a humidity sensor; wherein said method further comprises at least one member of the group consisting of the steps: first asserting a pitch actuation control signal for at least part of said take-off process based upon said temperature reading, said pressure reading, and said humidity reading; and second asserting said pitch actuation control signal for at least part of said touchdown process based upon said temperature reading, said pressure reading, and said humidity reading; wherein when said pitch actuation control signal is asserted, a pitch actuator stimulated by said pitch actuation control signal causes said pitch actuator to alter a pitch angle of said slider coupled through a flexure finger to said pitch actuator, wherein said CSS hard disk drive, includes: said slider coupled through a flexure finger to said pitch actuator, said temperature sensor, said humidity sensor, and said air pressure sensor.
