摘要： Embodiments of the present invention relate disk drives, and in particular to realizing a positioning accuracy equal to that of an actuator having the mountable maximum number of suspensions, in an actuator having the smaller number of suspensions than the mountable maximum number. An embodiment of a magnetic disk device includes an actuator having an arm to which a suspension for applying a predetermined load onto a slider with a magnetic head is attached, and an arm to which a plate is attached instead of having the suspension. The plate attached to the arm in place of the suspension has a partially small section with respect to a section perpendicular to an arm longitudinal direction (constricted part), and the constricted part is located between a plate leading end and an arm attachment part.

摘要： Embodiments of the present invention help to reduce out-of-plane excitation force exerted on a coil in a voice coil motor of a magnetic disk drive, so that vibration of a magnetic head is suppressed. According to one embodiment, a voice coil motor has a flat magnet that faces a coil, and generates a magnetic field, and yokes that apply the magnetic field generated by the magnet to the coil. The magnet is provided with a magnetic flux guiding section, absorbing leakage flux from the magnet, on a most distal end of the magnet as viewed from a pivot axis. A most distal part of the coil as viewed from the pivot axis, may be situated in an outer side with respect to the most distal end of the magnet, and the magnetic flux guiding section is provided between the most distal end of the magnet and the most distal part of the coil.

摘要： Embodiments of present invention help to realize a highly reliable magnetic disk drive by preventing a positional displacement between a magnetic head and a target track by decreasing restricting forces that a cover exerts on a base when the temperature is increased. According to one embodiment, a base is formed by aluminum die casting, has a concave, rectangular parallelepiped shape, and is formed with step portions at the four corners. A cover is a flat plate of stainless steel or iron. Four corner portions of the cover are bent to form step portions. The cover is fixed to the base at the four corners with bolts at two side positions (six positions in total). A gasket is inserted at that time to enhance the sealing performance. Since the gasket is a member like a rubber packing, it is necessary to press the gasket with the flat portions of the base and the cover To this end, the gasket is placed on top of the base step portions and the connection between the cover and the base at the four corners is made under the base step portions.
摘要翻译：本发明的实施例有助于通过在温度升高时通过减小盖施加在基座上的限制力来防止磁头和目标轨道之间的位置偏移来实现高度可靠的磁盘驱动。根据一个实施例，基座由铝压铸形成，具有凹形的长方体形状，并且在四个角部形成有台阶部分。盖是不锈钢或铁的平板。盖的四个角部弯曲以形成台阶部。盖子通过两个侧面位置的螺栓（总共六个位置）固定在四个角落的基座上。此时插入垫圈以增强密封性能。由于垫圈是像橡胶垫片的构件，因此需要用基座和盖子的平坦部分按压垫圈。为此，垫圈被放置在基座台阶部分的顶部，盖子和在四个角落处的基部形成在基底台阶部下方。

摘要： When a slider slides on a recording medium and a frictional force acts on the slider, an unstable vibration resulting from falling forward of the slider and a local stress are prevented from being generated. An attitude of the slider is stabilized, and the slider is kept in a steady contact with a disc. A rotary support mechanism is constituted by successively connecting one deformable portion, one rigid portion and another deformable portion to an upstream side of another rigid portion with a slider attached thereto in a recording medium movement direction. The another deformable portion is bonded to a support arm. While a predetermined pressing load is given to the slider by a spring portion, an intersection of an extension of a virtual line connecting the one and another deformable portions with the surface of the recording medium is positioned on the upstream side of a sliding point of the slider on the recording medium in the recording medium movement direction.

摘要： A ramp load type magnetic disk unit which prevents worn particles of a slide tab and a runway produced as a result of repetitive load/unload operations from falling onto the magnetic disk and which has low cost, high reliability and high recording density. A groove portion as a worn particle removing mechanism is provided at a home position on the runway where the magnetic head support assembly stands by after the unload operation is finished. At the groove portion, the magnetic head support assembly is vibrated at low frequencies to scrape off the particles. A worn particle collecting portion is provided near the groove portion so that an air flow generated by the rotation of the magnetic disk and directed toward the collecting portion blows the worn particles caught in the grooves into the particle collecting portion.

摘要： In magnetic disk structure having a high density, positioning errors (generally referred to as "flutter error") occur due to fluctuation (i.e., flutter) of a magnetic disk. As a result reading precision deteriorates. This is a significant problem in realizing a large capacity providing magnetic disk apparatus. This can be resolved by magnetic apparatus such that a suspension which holds a slider having a magnetic head at one end and which is attached to a supporting arm at the other end is inclined so that an interval between the suspension and the magnetic disk is small on the inner rim side and is large on the outer rim side with this arrangement the occurrence of the positioning error due to the fluctuation of a deformation of the magnetic disk is reduced, thereby enabling a high density recording of the magnetic disk.
