Method and apparatus for controlling head movement relative to a disk in an embedded servo system

摘要: A method and apparatus are provided in an embedded servo system for controllably moving, using a linear motor, carriage assembly one or more accompanying heads relative to disk surfaces. Each surface includes sectors reading writing information. also fields spaced between the read/write sectors. The have preset position information each of tracks on disk. is form Normal Quadrature generated signals used determine exact head when it located track centers. Using determined knowing target surface, distance remaining found. value position, velocity can be proper amount current supplied motor so that arrives at minimal time.
