ABSTRACT:
A velocity control apparatus for a disk drive of the type comprising a recording disk rotatable about its axis, an electromagnetic read/write head for reading data from and writing data onto tracks on a surface of the disk, and means coupled to the head and responsive to velocity command signals for controlling the direction and speed of movement of the head. The velocity control apparatus includes a memory divided into a plurality of sections respectively associated with different ranges of desired distances to be traveled by the head, each section containing a predetermined number of addressable storage locations together defining an approximation of a desired velocity trajectory curve for a desired distance to be traveled included within the range associated with said section.
