    摘要: Embodiments in accordance with the present invention increase the possibility that a servo track in which servo data is defective may be detected, greatly decreasing the possibility that a write error may occur during use by a user. According to one embodiment of the present invention, a defective area management method for a data storage device is provided. The data storage device comprises a head in which positions of read and write elements differ from each other in the radial direction of a disk. A defective area management method performs positioning of the head by reading out servo data written on the disk using the read element. The defective area management method comprises the steps of performing data write processing by use of the write element with the read element being positioned at a target position at which normal data reading is performed; and registering areas, as an error area, in a data track in which normal data writing is performed using a servo track including the target position if a predetermined error occurs in the data write processing.

    摘要: Embodiments of the present invention provide a defect registration method for performing defect registration of sectors on a magnetic disk. In one embodiment, a rectangular detection window is applied to each defect sector. A threshold value of the detection window is set at 2. In addition, an additional sector group is defined for the detection window. The additional sector group is a target of the defect registration if the number of defect sectors exceeds the threshold value. The additional sector group covers sectors that are not judged as defects in defect detection inspection, but that are expected to be potentially defective. Even if the detection window is applied to a defect sector, an additional sector group is not generated. However, if the detection window is applied to a defect sector, an additional sector group is generated. If the detection window is applied to a defect pattern, an additional sector group is generated.

    摘要: A plurality of communication terminals are coupled to one telephone line via a plural terminals communication controlling system having circuits for detecting on-hook/off-hook of the communication terminals and a time supervising circuit. In the case where a transmission side has no selection signal transmission function, a first communication terminal is called by the transmission side. Even if this first communication terminal is a telephone set and there is no response because of the absence of a called party, a second communication terminal is called after a predetermined period of time, so that a desired communication is established between the transmission side and the second communication terminal by using a facsimile as the second communication terminal.

    摘要: In an apparatus for manufacturing a taper leaf spring, by which after performing rolling on the edges of a sheet spring material in the direction of its breadth, rolling for tapering the sheet in the direction of its thickness is carried out, an edge roll assembly is employed for the sake of rolling in the breadth direction. In the edge roll assembly, constraining flanges for regulating the sheet thickness are provided on both ends of the main body of the edge roll so that expansion of both sides of a sheet spring material in the sheet thickness direction due to the effect of rolling in the sheet breadth direction is suppressed by the flanges and the thickness of a sheet spring material is kept uniform as a whole prior to performing rolling in the sheet thickness direction.

    摘要: Embodiments in accordance with the present invention relate to identifying an address of user data to be registered as a defective user data address in disk defect inspection. In an embodiment of the present invention, in the state where a write element is positioned to a target position to execute data write processing to execute normal data read processing, a write element executes data write processing. If a predefined error occurs during the data write processing, an address of user data for which the normal data write processing is executed is estimated using the error-causing servo data as a target. In addition, an address of the servo data used as the target during the normal data write processing for the estimated address of the user data is identified. If the identified address of the servo data and the address of the error-causing servo data match with each other, the estimated address of the user data is registered as a defective user data address.

    摘要: Embodiments in accordance with the present invention erase a desired area on a recording surface of disk or disk drive apparatus. According to an embodiment, a hard disk drive (HDD) performs erase on a recording surface by moving a head element unit at one-half a servo track pitch with reference to a servo address. Before actual erase is started on the recording surface, the HDD generates a management table configured based on servo addresses from a management table configured based on data tracks. At an erase process, the HDD sets parameters in accordance with the zone and skips a management area with reference to this management table based on the servo addresses.
