摘要： Systems and methods for a SSD controller enabling data transfer between a host and flash memories have been achieved. A major component of the SSD controller is a non-volatile buffer memory, which interfaces fast disk drive protocols and slow write and read cycles of NAND flash. Preferably MRAM or Phase Change RAM can be used for the buffer memory. Non-volatile tables can also be implemented for storing dynamic logical to physical address translation, defective sector information and their spare sectors and/or SSD configuration parameters. data are kept in a buffer memory when the buffer memory is not powered

摘要： A magnetic head is described for use in a disk drive having a disk that is rotated during operation of the disk drive and stationary when the disk drive is non-operational. The disk includes a surface containing data tracks. The magnetic head compromises a slider including a forward edge, a trailing edge and an air bearing surface. A read/write transducer is mounted at the trailing edge of the slider. The slider and transducer are mounted within the disk drive, relative to the surface of the rotating disk, to fly above the surface of the disk during rotation of the disk, for reading and writing data from and to the data tracks, and to come to rest on the surface of the disk during non-operation of the disk drive. An array of overcoat protrusions is formed on and spaced across the slider to cover a predetermined and discrete area of the slider in a manner so that when the slider and transducer come to rest on the surface of the disk, contact with the surface of the disk occurs only at the array of overcoat protrusions.

摘要： A thin film magnetic head has a configuration in which a main magnetic pole film having a magnetic pole end portion on a medium opposing surface (ABS) side facing a magnetic disk, a write shield film facing the magnetic pole end portion so as to form a recording gap film on the medium opposing surface side, and a thin film coil wound around at least a part of the write shield film are laminated. Further, the thin film magnetic head has an upper yoke magnetic pole film whose size is larger than that of the main magnetic pole film at a part more distant from the ABS than the recording gap film, and this upper yoke magnetic pole film is bonded to the side of the main magnetic pole film close to the thin film coil. In the upper yoke magnetic pole film, an end portion on the ABS side is retracted in a direction apart from the ABS in accordance with an increase in film thickness which is measured from the surface of the main magnetic pole film.
