Patent Number Title Of Patent Date Issued
5379439 Fixed disk drive mounted to printed circuit board January 3, 1995
A fixed disk memory subsystem connects to digital signal buses and a power supply of a host computer and includes a printed circuit board forming a subsystem mounting substrate for mounting and connecting a head and disk assembly and drive electronics. The head and disk assembly includes
5084791 Head position control system for fixed drive including position encoder, temperature sensor and January 28, 1992
A micro-Winchester disk drive subsystem includes a data block sequencer, cache memory and interface for a host computing machine. The drive includes a base and a plurality of non-removable directly rotated disks forming data storage surfaces. A balanced rotary head transducer actuator
5005089 High performance, high capacity micro-winchester disk drive April 2, 1991
A micro-Winchester disk drive subsystem includes a data block sequencer, cache memory and interface for a host computing machine. The drive includes a base and a plurality of non-removable directly rotated disks forming data storage surfaces. A balanced rotary head transducer actuator
4860194 A method for using a modular unitary disk file subsystem August 22, 1989
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
4772974 Compact head and disk assembly September 20, 1988
A compact, sealed head and disk assembly for a rotating non-removable disk data storage subsystem includes a flat and thin rigid generally rectangular box housing having a length not greater than approximately 173 millimeters, a width not greater than approximately 102 millimeters and a
4712146 Thin and compact micro-Winchester head and disk assembly December 8, 1987
A compact, sealed head and disk assembly for a rotating non-removable disk data storage subsystem includes a flat and thin rigid generally rectangular box housing; a thin spindle motor mounted within the form factor of the housing; a magnetic media data storage disk in the housing an
4703176 Compact polyphase optical position encoder October 27, 1987
A compact polyphase optical encoder subassembly for installation in host equipment is disclosed. The subassembly includes a moveable scale; and, a unitized rotatable housing for aligning a light source, a mask and a photodetector array having at least a pair of photodetector areas sy
4639863 Modular unitary disk file subsystem January 27, 1987
A self contained fixed rotating disk expansion board subsystem may be installed and connected at an expansion slot location of a host computer. The subsystem includes an enclosed head/disk assembly, and circuit elements mounted on a printed circuit board which includes a connector for
4538193 Aerodynamically released safety latch for data transducer assembly in rotating rigid disk data s August 27, 1985
An aerodynamically released safety shipping latch for a rotating disk data storage device is disclosed. A moveable airvane means adjacent a rotating disk is deflected by airflow generated by disk rotation from an at-rest biased first position to a second position. A safety latch communic
4516177 Rotating rigid disk data storage device May 7, 1985
An improved rotating disk data storage device is achieved in a combination of an optical encoder to detect data track crossings, a servo sector surface on one of a plurality of rotating data storage disks with the surface being filled with a pattern of alternating bursts which are read
