摘要： A magnetic circuit is provided in an enclosure that can efficiently generate magnetic flux from the enclosure, configuring a magnetic disk, to a magnetic disk. Thus, by providing such a magnetic circuit, a magnetic field different from that in other enclosure parts, that is, a local magnetic field, is generated from the magnetic circuit in case the disk device is set in an external magnetic field. Hence, this local magnetic field can effectively erase data in the magnetic disk. In particular, since the local magnetic field is generated even if the external magnetic field is weak, it is possible to not only suppress the demagnetization of permanent magnets used in the spindle motor at minimum, but also effectively erase data in the magnetic disk.

摘要： Embodiments in accordance with the present invention reduce the height of a head gimbal assembly (HGA) while maintaining the rigidity of a load beam. According to one embodiment of the present invention, an HGA includes a slider, a flexure, and a load beam. The load beam includes a flange formed to protrude to the opposite side to a magnetic disk at the edge of the load beam extending in the length-wise direction. The load beam has a recessed portion opened to the side opposing the magnetic disk and having an opening area larger than the area of the back surface of the slider opposing the flexure. The slider is provided in the recessed portion so that the position of the surface of the load beam is between a virtual surface including the surface of the slider opposing the magnetic disk and a virtual surface including the slider back surface.

摘要： The present invention provides an improved magnetic data storage and retrieval system, which can absorb external shock and is easily attached to a host system. By setting bumpers in the four corners of a magnetic data storage and retrieval system, external shock can be absorbed to prevent a magnetic disk from being displaced from the proper alignment with its spindle motor. With this arrangement, in the two corners on the end portion side of a guide groove formed in the base, pedestal surfaces are formed in one side of the guide groove, and plate-like bumpers and are set on the pedestals. Further, in the remaining two corners, insertion-type bumpers may be set and a label covering part of them may be affixed.

摘要： A hard disk drive has an enclosure with disk construction members and is characterized by covering the enclosure with an electrically conductive sheet. The electrically conductive sheet protects the drive regardless of which direction an ESD charge is applied. The electrically conductive sheet does not permit ESD to pass through the disk construction members stored in the enclosure. Therefore, it is possible to form a structure in which a GMR head or the like in an enclosure is not damaged due to ESD even if the enclosure is handled by a general end user. Moreover, the present invention relates to an electrically conductive sheet for covering at least both principal planes of the enclosure of a hard disk drive constituted as described above. Other modes of the invention include at least both principal planes of an enclosure being covered by the electrically conductive sheet in such a way that both sheets on both principal planes are electrically connected. In addition, portions where the enclosure contacts the disk construction members on both principal planes may also be covered and electrically interconnected. Furthermore, the electrically conductive sheet may be bonded to the surface of the enclosure by an adhesive, or provided with an opening at a position corresponding to an enclosure portion that must be brought into contact with an external atmosphere.

摘要： A positioning structure for a flexible cable having a movable portion is provided. In one embodiment, an FPC cable mounted to a base is received within a slit of a fixing plate. The FPC cable is disposed perpendicularly to a bottom surface of a base. On the fixing plate is provided a positioning reference which is spaced a predetermined distance from the bottom surface of the base. When the FPC cable is received into the slit, a part thereof is pushed against the bottom surface of the base to create an elastic force. An upper portion of a reinforcing plate affixed to the FPC cable for reinforcement comes into abutment against the positioning reference to establish a vertical position of the FPC cable.

In one embodiment, the yoke structure of a voice coil motor includes a base of a casing formed from a ferromagnetic material; an auxiliary yoke disposed so as to be magnetically coupled to the base; a magnet disposed so as to be magnetically coupled to a front surface of the auxiliary yoke; and a main yoke provided with yoke legs magnetically coupled to the auxiliary yoke and an opposing surface that confronts a front surface of the magnet. In addition, a yoke gap is defined between the opposing surface and the front surface of the magnet. The base and the auxiliary yoke form a magnetic path, which allows a dedicated yoke on a lower portion to be eliminated.
