摘要： PROBLEM TO BE SOLVED: To improve rigidity and surface hardness of a plastic material. SOLUTION: When ions produced from an ion source 13 are accelerated in an accelerating tube 17, the irradiation energy of ions is changed by controlling the electric field applied on the accelerating tube 17. Thereby, the density of ion irradiation in the depth direction on the surface of the object 20 is controlled and the distribution of Young's modulus is controlled.

摘要： PROBLEM TO BE SOLVED: To realize stable driving control of an objective lens driver which constitutes an optical head device and has a driving mechanism with three shafts or more including the driving shafts in the focusing direction and the tracking direction. SOLUTION: The objective lens driver 6 is provided with a movable part 7 which holds the objective lens 5 and is position-controlled in the focusing direction and the tracking direction with respect to a disk 2 is provided with a driving mechanism 9 for rotating the movable part 7 around the shaft with respect to a plane almost parallel with the disk 2, including the direction along a disk radial direction. By supplying a driving signal with a waveform obtained by combining a direct current voltage component or a low frequency alternating current component and high frequency alternating current voltage component to a driving coil constituting the driving mechanism 9, the influence of static friction in the driving mechanism 9 is relieved and an influence resulting from having a hysteresis characteristic in relation to a position and an angle corresponding to a driving voltage value is reduced.

摘要： PROBLEM TO BE SOLVED: To provide the dynamic pressure fluid bearing capable of more suppressing a rotary shake than heretofore. SOLUTION: A rotary thrust plate 115 is formed to be gradually thicker from the inner circumferential side to the outer circumferential side, and an upper surface 116a of a bearing part 116 to be opposite to a lower surface 115a of this rotary thrust plate 115 is formed to be flat surface. Consequently, a gap between the lower surface 115a of the rotary thrust plate 115 and the upper surface 116a of the bearing part 116 is gradually narrower toward the outer circumferential side. When the rotary thrust plate 115 is rotated, a lubricant fluid on the discoid surface is moved to the outer circumferential side, whereas since the gap with the bearing part 116 is narrower toward the outer circumferential side, the lubricant fluid is most compressed on the outermost circumferential side so that a dynamic pressure is generated. By this dynamic pressure of the lubricant fluid, a thrust load can be supported.

摘要： PROBLEM TO BE SOLVED: To prevent occurrence of damage of a magnetic disk and a head slider when the head slider is brought into contact and collision with the disk, and to afford high durability and high reliability to a disk drive device. SOLUTION: Impact buffer material 800 which consists of high polymer material is disposed on the side opposite to the surface of the head slider 604 opposed to the disk, and, thereby, amplitude and kinetic energy of the head slider at the time of occurrence of impact can be absorbed. Concretely, by adopting constitution of the impact buffer material which has gel material as a constitutional element, multilayer constitution which combines a receiving plate part 801 with an impact buffer part 802 and constitution which exhibits energy absorbing effect owing to a thin plate part, etc., and, further, constituting the device in such a manner that the impact buffer member is not brought into contact with gimbals which performs attitude control of the head slider, the possibility of the occurrence of damage of the disk and the head slider when the head slider is brought into contact and collision with the disk is reduced.

摘要： PROBLEM TO BE SOLVED: To improve the durability and suppress the run-out of a rotary shaft. SOLUTION: Herringbone grooves 111 are cut in the lower part of the outer peripheral surface of a rotary shaft 106. Plural notches 11 are formed on the outer periphery of a rotary thrust plate 10 in which the rotary shaft 106 is fitted and fixed. Lubricating fluid is sealed between the rotary shaft 106 and the rotary thrust plate 10, and bearing surfaces 113 or the inside surface of a shaft hole. When the rotary shaft 106 and the rotary thrust plate 10 are rotated, pressure is generated by the herringbone grooves 111 to support radial load. Further, pressure is generated by the notches 11 in the neighborhood of the outer periphery of the rotary thrust plate 10 to receive thrust load. Furthermore, since the lubricating fluid is efficiently circulated by the notches 11, the frictional loss is reduced to enhance the durability, and thus to suppress the rotational run-out.

摘要： PROBLEM TO BE SOLVED: To constitute a hard disk device compatible with recording density. SOLUTION: A hard disk 12 having a guard band constituted of grooves formed ranging the whole surface of a data recording area is housed in a cartridge, and this cartridge is loaded attachably/detachably on a device main body. The hard disk 12 is formed so that a depth and an area of the groove 54 for the guard band are different so that a head floating amount is different in a low density recording disk and a high density recording disk. In the case of high density recording, when the groove 54 is made deep even in the same width, load capacity is reduced, and the head floating amount is reduced. Since a spacing loss is reduced by such much, it becomes the high density recording head floating amount. In such a manner, a compatible removable hard disk device is realized only by revising the groove 54.

摘要： PROBLEM TO BE SOLVED: To measure a force acting in the vertical direction to a head slider in a dynamic load/unload system disk by providing a measurement control part. SOLUTION: The evaluation device has a disk 13 that is rotated and driven, a spindle motor 12 for rotating and driving the disk 13, a head support part 14 consisting of a head slider 14a and an elastic support member 14b, and a measurement control part 15. The measurement control part 15 has a movable part 15a that moves up and down, a sensor part 15b that is provided at the movable part 15a, a motor part 15c that drives the movable part 15a up and down, and a substrate 15d that is mounted to the movable part 15a. A thin plate 15d is provided between the surface of the disk 13 and an elastic support member 14b and at the same time lifts up the elastic support member 14b when it is driven up and down, thus measuring a force that is applied to the thin plate 15d using a sensor part 15b. Forces that are supplied to the elastic support member 14b and the head slider 14a are measured for a direction that is vertical to the surface of the disk 13.
