Abstract: An architecture for a low profile disk drive device wherein a lower surface (21) of an information bearing disk (20) abutting an upper surface (28) of a spindle motor (10) is not accessed by a read/write head (30) for data storage or retrieval. The disk (20) is used as a magnetic shield to protect reading and writing from an upper surface (22) of the disk (20). The architecture facilitates lower profile construction because the spindle motor (10) can be made with a larger diameter and thinner height. Memory capacity is not sacrificed because a greater portion of the remaining disk surfaces is utilized.

Abstract: The prerecorded embedded servo field (300) of this invention provides an enhanced level of functionality without increasing the servo field overhead. A prerecorded embedded servo field (300) includes a first sub-field (302) of prerecorded information that simultaneously provides (i) automatic gain control data for a third sub-field (306) and (ii) data for a first servo function, and a second sub-field (302) of prerecorded information that simultaneously provides (i) automatic gain control (AGC) data for the third sub-field (306) and (ii) data for a second servo function. Since the first and the second sub-fields (302, 303) in the servo field (300) of this invention are used for AGC and another servo function, the sub-fields are arranged within the servo field (300) so that the sub-field (302) that requires the least precise AGC control is first and the sub-field (306) that requires the most precise AGC control is last.

Abstract: A spin motor assembly (10) of a disk drive apparatus includes a stator (56) having a plurality of wound coils (38), (40), (42), (44), (46), (48), (50), (52), (54), associated therewith, and a rotor (64) having a plurality of magnetic poles. Each winding structure of the stator (56) is made up of two winding portions, with only one winding portion being used to drive the rotor (64) relative to the stator (56) upon drive current being applied to the winding structure, but with both winding portions being used to generate back electromotive force when drive current is cut off from the winding structure. This generated electromotive force is used to actuate an actuator motor (120) to unload the read-write heads from the disk surface. As an alternative, each winding structure of the stator (56) is made of a single winding, and the winding structures are used successively to drive the rotor (64) relative to the stator (56), but with at least two winding portions generating back electromotive force when drive current is cut off.

Abstract: A silent seek servo controller (400) is used in a low profile miniature disk drive (300) to minimize acoustic noise and the problems associated therewith. Silent seek servo controller (400) of this invention reduces acoustic noise generation at the expense of seek performance. Since the silent seek servo controller (400) of this invention minimizes acoustic noise, the controller (400) helps to eliminate vibration within a computer. The silent seek servo controller (400) that accelerates and decelerates an actuator (415) using a smooth, continuous and completely symmetric acceleration trajectory. The symmetry of each acceleration phase assures that any acoustic noise generated by uneven acceleration is eliminated.
