摘要： A disk-drive-compatible magnetic tape cartridge is provided with a tape guide for accurately positioning a magnetic tape in relation to a disk drive head. The tape guide includes a positioning section to be aligned with a rotation axis of a center core assembly when the center core assembly is chucked on a turntable of the disk drive. The tape guide also includes a guide section defining a tape run path across the disk drive head. The guide section is formed integrally with the section to be aligned with the center core assembly and so distanced from the latter as to accurately position the magnetic tape with respect to the disk drive head. Since the tape guide has the positioning section and guide section integrally, the distance therebetween can be maintained precisely constant. Therefore, tracking by the disk drive head becomes easier to allow high-density recording.

摘要： An electrophoretic cell and methods of switching an electrophoretic cell and moving charged species in an electrophoretic cell employ differential electrophoretic mobilities and a time-varying electric field. The methods include providing first and second charged species that are oppositely charged and have different mobilities. The method of switching further includes inducing a net motion of both of the charged species using the time-varying applied electric field. The induced net motion results in either the first charged species being moved toward the electrode and the second charged species remaining essentially motionless or both of the charged species being moved toward the same electrode. The electrophoretic cell includes the first and second charged species with opposite charge and different mobilities, and further includes the time-varying applied electric field that provides the net motion of the charged species.

摘要： A batch fabrication technique is described that increases the manufacturing efficiency of servo write heads and also improves servo pattern definition for fine features, while reducing tape and head wear. Multiple heads are fabricated as a batch from one or more ferrite wafers. A nominally flat, large wafer surface and a contour suitable for uniform photoresist application and planar photolithography permit fine servo pattern definition. A rounded leading edge on the head creates an air bearing to reduce wear of the tape and of the head. Moreover, any head wear occurs at the leading edge rather than in the region of the head where the servo pattern is formed. The servo write head may have a substantially planar head surface. A leading edge is disposed adjacent to the head surface such that the tape contacts the leading edge before passing over the head surface. The leading edge is rounded to form an air bearing between the head surface and the tape. A rounded trailing edge may be disposed adjacent to the head surface such that the tape passes over the trailing edge after passing over the head surface. The head may be formed from an upper ferrite wafer having a non-magnetic spacer. Non-magnetic material is photolithographically defined to produce gaps above the spacer. The non-magnetic material may be photoresist, semiconductor materials, glass, metal or the like. The material may even be removed later to leave air gaps. The non-magnetic material forms a region where the field loops out to intersect the passing tape, thereby transferring a magnetic pattern to tape. Additionally, a lower ferrite wafer may be mated to the upper ferrite wafer to complete a magnetic circuit around the gaps. The upper or lower ferrite wafer may have a channel through which an inductive winding passes. Multiple heads may be formed through batch processing of the upper and lower ferrite wafers.

摘要： A process and apparatus is described to break down the Position Error Signal (PES) of a magnetic or optical disk or tape drive to its contributing components. (In the case of the optical disk drive, the method is actually two different PESs, Focus Error Signal (FES) and Tracking Error Signal (TES).) This method is based on three concepts: an understanding of how Bode's Integral Theorem ties into noise measurements, a measurement methodology that allows for the isolation of individual noise sources, and a system model that allows these sources to be recombined to form the drive's Position Error Signal. The method measures frequency response functions and output power spectra of each servo system element. Each input noise spectrum can then be inferred and applied to the closed loop model to determine its effect on the PES uncertainty. The method allows the user to identify and rank the most critical noise sources in the positioning mechanism of a drive. This allows for optimization of the drive positioning control loop(s) by suitable design choices. Such choices may include--but are not limited to--optimization of the position encoding on the data storage surface (such as groove dimensions in an optical drive), optimization of the position signal detection method (such as the demodulation method on a magnetic disk or tape drive), and optimization of the actuator design. Such optimization is far more difficult without this invention because it is very difficult to identify which improvements are most helpful.
