摘要： A network storage device having a network controller card and a data storage device is described herein the card and storage device are either enclosed in a small from factor unit or assembled together to fit within a standard hard disk drive bay in a computer. The combination of a controller card and storage device is designed to transfer files from and to a network using standard network file protocols. As the network storage device does not process the files, much of the computational overhead of a network server can be eliminated, resulting in a simpler device capable of faster file exchange.

A bidirectionally moveable electromechanical mover includes a microstep providing stepping motor supported by the frame.

A data track stabilization means includes the stepping motor and stabilizes the structure within a range between the boundaries of each data track. A time sampled fine position closed loop servo is connected to the driver and includes a single, data masked servo sector on a data surface of said disk containing track centerline servo control data therein readable by said head, a sample and hold circuit connected to the head during passes over the servo sector for holding control data read therefrom, and a correction signal generator connected to the sample and hold circuit for generating an offset signal for application to said driver to promote and maintain track centerline alignment of the head during read and write operations.

摘要： A servo calibration method is disclosed for a disk drive including a rotating data storage disk journalled to a frame and having a multiplicity of concentric data tracks defined on a major surface thereof and an actuator structure under the control of a programmed servo control microprocessor in response to coarse position information fed back to the microprocessor by a position encoder, and to fine position information fed back to the microprocessor by a data transducer reading from servo information prerecorded on the major surface of the disk, the actuator structure for moving the data transducer to each selected one of the data tracks during track seeking operations and for maintaining the transducer aligned with the data track during track following data read and/or write operations. Carried out during initialization, the method includes the steps of: automatically seeking to a region of radially outermost tracks, reading fine position information recorded in the single sector of each of a plurality of outermost tracks, and recording the outer track fine position information in memory; automatically seeking to a region of radially innermost tracks, reading fine position information recorded in the single sector of each of a plurality of innermost tracks, and recording the inner track fine position information in memory; for each data track to which a seek is initially commanded, which track lies between the outermost track region and the innermost track region, calculating with the microprocessor means a track centerline correction value lying between the outer track fine position information and the inner track fine position information, and applying the track centerline correction value so calculated as an offset value to the rotary actuator to correct any discrepancy between nominal track centerline defined by the position encoder.

摘要： In an optical encoder with a single light source, an array of a plurality of spaced photodetectors formed on a common substrate, a reticle disposed in fixed position relative to said photodetector array, and a scale of alternating translucent and opaque regions relatively moveable between said light source and said reticle so as to cause said array to provide a plurality of phase related analog signals whose amplitudes vary with the position of said scale, an improved digital automatic gain control is disclosed. A digital switch selects one of said analog signals and an analog to digital converter converts and puts out the selected signal as a digital value. A programmed microprocessor reads each such digitized signal, determines the signal value corresponding to maximum light transmission, compares said value with a nominal reference value, and computes a correction value therefrom. The microprocessor stores said correction value and thereafter puts it out as a digital value to a digital to analog converter which converts it into an analog electrical signal. An amplifier drives said light source in accordance with each said analog electrical signal, so that the optical encoder operates said single light source to yield a light value which has been digitally measured and corrected to a nominal value for each photodetector of said array.

摘要： An improved apparatus and method is disclosed for controlling the position of one moveable member relative to another. In the disclosed preferred embodiment of a rotating disk memory system, the moving member is a head carriage structure and the other is a frame carrying a rotating data storage disk. From externally supplied position selectron information, and from internally determined polyphase position information, open loop position changing movements are determined and carried out in accordance with monitored incremental polyphase position information generated during the movement. When a destination location has been reached one or more servo systems close loop in order to maintain the moving member precisely at the newly commanded location. A rotor for moving the member is an aspect of the present invention.

摘要： A modular unitary disk file subsystem is used directly with a host computer. The subsystem includes a common unitary mounting substrate for power and signal connections to the host and for supplying control and data signals back via data, address and control buses to the host computer through a direct plug-in connection without any cabling between the subsystem and the host. The substrate carries and interconnects a unitary disk store head and disk assembly, a disk store control, a disk file controller, and a data and control interface with the computer. The modular unitary plugin form factor, a single supervisory microcomputer controller and a memory containing basic input/output driver routines directly executable by the host computer allow the subsystem to be transported easily between host computers.

摘要： Improvements in a system for controlling the position of a head carriage structure of a rotating disk data storage system are disclosed. The improvements include circuitry for generating a polyphase track boundary signal which compensates for drift, and which doubles or further increases the track density to increase storage capacity. A track centerline sensor circuit is greatly simplified by including the function thereof as microcode routines within a dedicated digital control processor. Error signals are measured periodically across the entire useful field of the disk, and they are constantly updated, so that improved compensation for drift, runout and offset of the disk relative to the data transducer is achieved. Track overshoot during track seeking movements of the transducer is accomodated, enabling reduced track average access time. Self contained diagnostic routines and a direct digital read out provide system status and error messages to operators and maintenance personnel, thereby facilitating maintenance and adjustment.
