  • Adaptive track seeking for disk drives
    Patent number: 5305161
    Abstract: A method and apparatus for optimizing the track seeking operation of disc drives by adaptively changing the seek velocity profile in response to the actual performance of the drive during track seeking operations based upon the amount of head overshoot and the actuator power dissipation.

  • Magnetic tachometer for disk drives
    Patent number: 4622516
    Abstract: A magnetic tachometer for generating a signal as a function of the velocity of a transducer positioning arm in a disk drive. The tachometer is formed by a pair of fixed parallel coils separated by a distance sufficient to allow a magnet, attached to a counterbalance portion of the rotary positioning arm, to move therebetween and thus to generate a voltage as a function of the velocity of the magnet. The coils are each wound over a thin armature member which is saturated by the magnet's magnetic field and they are differentially coupled to produce common mode rejection.
