    • A patterned magnetic storage medium (107) has a plurality of data sectors (314) separated by respective servo sectors (310) with each servo sector having a pattern of pits (318) representing servo data. Grooves (322) in each data sector separate adjacent tracks. Non-uniform means, such as lands (324) patterns the grooves (322) to a model of minimum or zero fly height perturbations of a slider adjacent the medium. The non-uniform means preferably comprises lands (324) pseudo-randomly spaced along each groove (322) to form segmented grooves of pseudo-randomly length, with the lands being pseudo-randomly positioned across the data sector. In other embodiments, the servo sectors (310) have lengths (Ls) along each track (312) to define a null frequency (Fnull) that matches a pitch frequency of modulation of a slider due to the pits of the servo sectors.

    • Apparatus and method for improving operational performance of a disc drive (100) by detecting and compensating for translational vibration modes in a disc drive actuator (110). The actuator (110) is configured to support a head (120) adjacent a recording disc (106) and pivots about a stationary shaft (132) by way of a cartridge bearing assembly (112) having a pair of ball bearing assemblies (140). A proximity probe (130) detects translational movement of the actuator assembly (110) relative to the shaft (132) due to, for example, abrupt acceleration and deceleration of the head (120) during a seek operation, or externally applied mechanical shocks. The output of the proximity probe is used to generate a bearing translation signal which is fed into an actuator control servo circuit (176) to modify the amount of current applied to an actuator motor (114) to compensate for the translational vibrations during track following and seek operations.

    • A fly height controller (40) circuit for a disk drive head having a resistive heater is disclosed. The fly height controller includes an error amplifier (44) that controls a variable current source (46) driving the resistive heater. The error amplifier compares a desired heater power signal with a feedback power signal that is generated by a multiplier (50). The multiplier receives a signal corresponding to the resistive heater current, for example as generated by a second variable current source also controlled by the error amplifier, and a signal corresponding to a voltage across the resistive heater. A first differential amplifier develops a differential voltage corresponding to the heater voltage. A second differential amplifier is biased by the resistive heater current signal, and receives the differential voltage form the first differential amplifier. A differential current generated by the second differential amplifier produces the feedback power signal as an output voltage.
