摘要： A method and apparatus are provided to compensate for the runout that commonly occurs during the reading from or writing of information on the surface of a disk medium using a read/write head. The runout relates to the distance the head is located away from a disk track center during the rotation of the disk. To maintain the head in alignment with the track center during the complete revolution of the disk, position information is obtained. This position information is used with discrete fourier transform techniques to provide a representation of the disk runout. From this representation, a compensating signal can be generated to provide movement of the head that compensates for the runout and keeps the head positioned in alignment with the track center at all times during the disk rotation.

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

摘要： The control system manages the storage and retrieval of data with respect to a rotating media, wherein an actuator is utilized in the selection of data for storage and retrieval. The control system includes a low level media control circuit that permits the selection of the rotational position of the rotating media and an actuator control circuit that permits the selection of the position of the actuator with respect to the rotating media. A system controller is utilized to direct the operation of the low level media and actuator control circuits whereby the system controller specifies and adjusts, in real time, the incremental selection of the rotational position of the rotating media and the position of the actuator with respect to the rotating media. In the preferred embodiment of the present invention, the system controller is a programmable microcontroller operating in closed loop, event driven response to the occurrence of control information and data stored by the rotating media so that all essential operation required for the successful storage and retrieval of data with respect to the rotating media are performed concurrently and in real time by the microcontroller.

摘要： The software system architecture supports a rotating media in the storage and retrieval of data, where the rotating media stores in data tracks of multiple sectors, through the use of a microcontroller for the execution of a control program that schedules plural control tasks temporally distributed for respective execution during the rotational period of a predetermined track and sector. The scheduling of the plural control tasks is synchronized with respect to data retrieved from the predetermined sector. The plural control tasks include a rotational control task for determining an adjustment to the spin speed of the rotating media, a track following task for determining an adjustment to the alignment of the read/write head with respect to the predetermined track and a sector timing task for determining the position of the read/write head with respect to the predetermined track. The sector timing task also provides for scheduling the rotation control and track following task for execution during discrete intervals during the rotational period of the predetermined sector as well as scheduling the re-execution of the sector timing task with respect to the rotational period of another predetermined sector.

摘要： A disk drive control architecture provides for the storage and retrieval of data with respect to a rotating media and for the transfer of data with respect to a host in response to host commands. The control architecture provides for the execution of a plurality of background processes for controlling the spin speed of the rotating media, controlling the positioning of the sensor and controlling the reading and writing of data with respect to the rotating media. The control architecture further provides for foreground processes for controlling the background processes. The foreground processes include an interface task, for coordinating the background processes in the execution of host commands and a monitor task integral to the interface task such that the monitor task is capable of implementing diagnostic commands capable of accessing all of the resources of the control architecture. The transfer of diagnostic commands and resultant diagnostic information may be directed through a dedicated data communications channel separate from the data channel used for the transfer of commands and data with respect to the host.
