Abstract

An optical data-storage hard disk drive, which uses stationary Magneto-Optical Microhead Array Chips in place of conventional Flying-Heads, Rotary Voice-Coil Actuators and other similar types of Servo-Tracking mechanisms to transcribe or retrieve digital information to or from at least one non-volatile memory medium's data-surface, using an optical magnetic process of recording and reading data. The Magneto-Optical Microhead Array Chip Hard Disk Drives will have at least one storage disk-platter with two disk-platter data-surfaces containing a multiplicity of concentric data-tracks that rotates at a substantially constant angular velocity. Every Magneto-Optical Microhead Array Chip will comprise a (VCSEL) 'Vertical Cavity Surface Emitting Laser' microhead array having a minimum of one thousand or a maximum of four billion individually addressable VCSELs. Each Magneto-Optical Microhead Array Chip is placed into a stationary position above each disk platter data-surface using a chip-positioning circuit board. While the number of cylinder/tracks available to each Magneto-Optical Microhead Array Chip is determined by the number of VCSEL microheads contained within a Magneto-Optical Microhead Array Chip's microhead array (e.g., '325,000' vertical cavity surface emitting laser microheads would therefore equal '325,000' corresponding cylinder/tracks).
