Magnetic data storage fixed hard disk drive using stationary microhead array chips in place of flying-heads and rotary voice-coil actuators

A dedicated head-to-track data-storage fixed disk drive that uses a multitude of stationary microheads instead of conventional flying-heads, flying-head rotary voice-coil actuators, or flying-head rotary positioners to store or retrieve data magnetically to or from disk-platter data-surfaces, comprising:

• a) an enclosure providing for the installation of the components used in said fixed disk drive,
• b) at least one parallel circuit allowing transference of electrical impulses to or from at least one connected plurality of microscopic microhead transducers and at least one integrated circuit comprising a system controlling central processing unit,
• c) an arrangement of coils and magnets that convert electric current into mechanical power providing for rotation of at least one non-volatile data-storage memory medium,
• d) at least one rotatable non-volatile data-storage memory medium having at least one data-surface used in the transcription or retrieval of said digital information to or from said disk-platter data-surfaces, and
• e) a plurality of microhead data-transducers positioned into stationary locations above said disk-platter data-surfaces of said rotatable non-volatile data-storage memory medium,
• whereby, a stationary microhead positioned above a host requested cylinder-track location is switched on, while a different stationary microhead positioned above a previously requested cylinder-track location is simultaneously switched off, and
• whereby, average-seek-times of said dedicated head-to-track data-storage fixed disk drive is greatly decreased over said average-seek-times of flying-head magnetic or flying-head optical hard disk drives.

A microhead array chip hard disk drive that stores data magnetically using stationary microhead array chips instead of conventional flying-heads and rotary positioners, comprising:

• a) an enclosure comprising a casting-base, a gasket, and a cover,
• b) a printed circuit board disk controller,
• c) a spindle-motor unit assembly,
• d) at least one stationary positioned microhead array chip comprising a multitude of stationary microheads, and
• e) at least one ferrite coated disk-platter comprising two data-surfaces having a multiplicity of concentric data-tracks, which are used for data-storage, while being rotated at a substantially constant angular velocity.
• whereby, advantages of a plurality of stationary microheads positioned above dedicated cylinder-track locations is clearly seen, and
• whereby, said average-seek-times occurring within said microhead array chip hard disk drive are so fast they are measured in nanoseconds, a time-scale three orders of magnitude faster than a millisecond time-scale normally used to measure said average-seek-times occurring within flying-head hard disk drives.
