Abstract

A magnetic data storage fixed hard disk drive using stationary Microhead Array Chips in place of conventional Flying-Heads and Rotary Voice-Coil Actuators or other Servo-Tracking mechanisms. Every Microhead Array Chip has a minimum of one thousand or maximum of four billion individual and addressable microhead read and write data-transducers built into it. The hard disk drive unit assembly that uses the Microhead Array Chip approach will have within its assembly as few as two or as many as twenty-eight installed Microhead Array Chips. The Microhead Array Chip hard disk drive unit assemblies 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. While Microhead Array Chips are made stationary by specially designed circuit boards, that positions a Microhead Array Chip over each of two data-surfaces of every disk-platter within the hard disk drive assembly. The total number of microheads within a stationary positioned Microhead Array Chip's Microhead Array is what determines the total number of available tracks on and across a data-platter's data-surface (i.e., 65,000 microheads would equal 65,000 cylinder/tracks).
