    摘要: A method for managing a memory stack provides mapping a part of the memory stack to a span of fast memory and a part of the memory stack to a span of slow memory, wherein the fast memory provides access speed substantially higher than the access speed provided by the slow memory.

    摘要: A system for controlling movement of a head over tracks on a disc in a disc drive includes a servo positioner for positioning the head over a desired track, a sectoring circuit for determining when the head is over a data sector on the desired track, a formatter for controlling data transfers to and from the desired track, and a controller for providing the servo positioner with a track address indicative of the desired track. A track change system is coupled to the formatter and the servo positioner, and provides a direct communication channel between the servo positioner and the formatter. Thus, the data transfer can be carried out utilizing communications between the formatter and the servo positioner, without waiting for the microcontroller to be interrupted.
