摘要： Methods of controlling seeking of a transducer that is adjacent to a rotatable disk in a disk drive are disclosed. The methods may include accelerating the transducer radially across the rotatable disk from an initial track on the rotatable disk toward a destination track on the rotatable disk, estimating a deceleration switching position/velocity point, estimating a maximum deceleration position/velocity point following the deceleration switching position/velocity point, and estimating a deceleration current required to decelerate the transducer from a non-zero velocity at the maximum deceleration position/velocity point to zero velocity at the destination track. The estimated deceleration current is compared to a maximum available deceleration current, and responsive to a determination that the current required to decelerate the transducer from the maximum deceleration point to the destination track exceeds the maximum available deceleration current, the estimated deceleration switching point is adjusted. Related disk drive apparatus are also disclosed.

摘要： A disk drive includes a disk, a head, a coarse actuator, a microactuator, and a servo controller. The microactuator positions the head relative to the disk. The coarse actuator positions the microactuator and the head relative to the disk. The servo controller controls the microactuator in accordance with a microactuator feedforward control signal that is provided by the servo controller based on a plurality of microactuator feedforward values. The servo controller tunes at least one microactuator feedforward value of the plurality of microactuator feedforward values. The servo controller scales the microactuator feedforward control signal in accordance with a microactuator feedforward gain, and the servo controller adjusts the microactuator feedforward gain based on a position error signal that is determined during a seek operation.

摘要： A method of fabricating a memory device having a core region of double-bit memory cells and a periphery region of logic circuitry includes forming a dielectric stack over the core and periphery areas of a semiconductor substrate and removing the dielectric stack from the periphery region. A gate dielectric is formed over the periphery area, followed by a first conductive layer over the core and periphery areas. After the formation and thermal processing of the gate dielectric, bitlines, which serve as source and drain regions, are implanted into the core area. Formation of the bitlines after the gate dielectric layer reduces lateral bitline diffusion and reduces short channel effects.
