摘要： A magnetic disk drive has a housing for a 3.5 inch form factor and disk media of a diameter for a 2.5 inch form factor. The smaller disk media rotate at a high speed while consuming low electric lower and generating less heat while providing for quick access speeds. Usually, when the magnetic disk media are rotated at a higher speed, the electric power consumption and heat generation are increased because of the load increase. This problem is avoided with the use of cooling fins placed about the periphery of the disk media. Further, the smaller size disk media enable a decrease in torque loss during on-load rotation with the media, and a decrease of electric current to the spindle motor during rotation.

摘要： A magnetic disk apparatus includes a magnetic disk, a magnetic head for writing data into and reading data from the magnetic disk, a carriage pivoted on a pivot bearing while holding the magnetic head at its one end, the pivot bearing being constituted by a cylindrical sleeve serving as a fixed axle, bearing units each having an outer race fitted to the inside of the sleeve, bearing balls, and an inner race, and a shaft having the outside fitted to the inner races of the bearing units, thus, change of a pre-load caused by a heat expansion difference between the shaft and sleeve is an axial direction is compensated with a change of a pre-load caused thereby the same is a radius direction. Hence, the weight of a pivotally movable portion of an actuator is reduced.

The disk drive includes: a head for accessing a data recording area of a disk; an actuator for pivoting to move the head; a voice coil motor; and, a latch configured to lock the actuator from pivoting toward the data recording area in response to an external force. The voice-coil motor includes a voice coil, a magnet, and a yoke. The latch is positioned at a closed position when the actuator is positioned at a stand-by position, and is configured to pivot by application of a magnetic bias force with pivoting of the actuator from the stand-by position into proximity with the data recording area such that the latch is configured to stop at an open position. The yoke includes a protrusion which protrudes toward the magnetic body at the open position.

摘要： In a closed housing of a magnetic disk memory device are accommodated a spindle motor for rotatably holding a magnetic disk medium for storage of information, a magnetic head for recording and reproducing information into and from the magnetic disk medium, a head positioning mechanism for moving the magnetic head to any position on the magnetic disk medium, and so forth. A printed board having thereon control circuit parts for controlling the spindle motor and the head positioning mechanism and recording/reproducing circuit parts for effecting the recording/reproduction by the magnetic head is arranged outside of the housing. An opening corresponding to a component of the magnetic disk memory device is formed in a certain region of the housing opposing the printed board. A shielding member for preventing a dust from entering into the housing is provided for the opening. The shielding member has a sheet-like or cup-like form and the device is constructed corresponding to the unevenness or uneven arrangement of components, thereby making it possible to reduce the thickness of the device. The commonization of the shielding member for disk devices is possible and a distance between a printed board and the housing can be reduced for the whole of the device.
