摘要： PROBLEM TO BE SOLVED: To provide a data management in a flash memory using probability of charge disturbances.SOLUTION: A Flash memory system and a method for data management using the system's sensitivity to charge-disturbing operations and the history of charge-disturbing operations executed by the system are described. In an embodiment of the invention, the sensitivity to charge-disturbing operations is embodied in a disturb-strength matrix in which selected operations have an associated numerical value that is an estimate of the relative strength of that operation to cause disturbances in charge that result in data errors. The disturb-strength matrix can also include the direction of the error which indicates either a gain or loss of charge. The disturb-strength matrix can be determined by the device conducting a self-test in which charge-disturb errors are provoked by executing a selected operation until a detectable error occurs.

摘要： PROBLEM TO BE SOLVED: To provide a head with an altitude resistant air-bearing surface.SOLUTION: There are provided approaches for a head slider for use within a hard-disk drive. The head slider comprises an air bearing surface (ABS) and an electromagnetic transducer disposed at an air outflow end of the air bearing surface. The air bearing surface comprises a slit feature that is present prior to the electromagnetic transducer in the direction of air flow. The physical dimensions of the slit feature are designed to lower an amount of pressure required for a protrusion of the head slider to detect a surface of a magnetic-recording disk. The air bearing surface may further comprise an optional hollow recess prior to the slit feature in the direction of air flow. The size and the shape of the hollow recess are designed to decrease a change in a fly height of the head slider in response to a change in altitude of the hard-disk drive.

摘要： PROBLEM TO BE SOLVED: To provide a dielectric body window processing of wide bandwidth for a conductor suspension structure.SOLUTION: The present invention relates to a suspension mutual connecting part of a hard disk drive with wide bandwidth. The suspension mutual connecting part includes a substrate layer, a dielectric body layer arranged on the substrate layer, and a plurality of transmission lines (TLs) arranged in the dielectric body layer. Voids are arranged around the TLs so that the tendency that a dielectric material functions as a shunt hindering high bandwidth signal transmission can be minimized. In the dielectric body layer, there are voids between the TLs adjacent to each other. In addition, the dielectric material and the voids can be arranged alternately in the region adjacent to the plurality of TLs along the direction in which signals moves. Besides a plurality of dielectric body ties imparting structural support to the TLs, no solid material surrounding the TLs is needed. The substrate layer can also include one or more voids under a part of the plurality of TLs.
