摘要： Apparatus and method for compensating for servo data distortion during a seek operation (250) in a disc drive (100). A seek is initiated (252) to move a head (118) from an initial track to a destination track on a disc (108). Servo data (154) from intermediary tracks are decoded by generating nominally redundant positive and negative digital pulse streams (180, 182) from positive and negative digital peaks (172, 174) in a servo data readback signal (170), and then combining the positive and negative digital pulse streams using a first Boolean logic operator (196) to qualify pulses in a first output digital pulse stream (184) indicative of head position. When distortion arises in the servo data readback signal that prevents correct detection of head position (258), the head is brought to rest (264), a second Boolean logic operator (198) is selected (266), and the seek is resumed (270) using the second Boolean operator. A table (202) stores the most recently selected Boolean operator for each head.

摘要： An apparatus and method for determining the configuration of a disc drive (100) head-disc assembly (HDA) (101). The HDA includes an array of rotatable discs (106) and an actuator assembly (110) adjacent the discs, with the actuator assembly supporting a maximum number of heads (120) in a fully populated configuration and a reduced number of heads in a depopulated configuration. Each head is disposed at a unique head position. During each spin-up of the disc drive, a servo circuit (148) determines an impedance of a selected head position having a head when the disc drive is fully populated, but not when the disc drive is depopulated. The servo circuit identifies the configuration of the HDA in relation to the determined impedance, and initializes the drive accordingly.
