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： The vehicular door lock device includes a casing fixed to a door and having a bulged portion defining an ingress passage receiving a striker on a vehicle body. A latch is supported on the casing for engagement with the striker for turning movement. A ratchet on the casing is for engagement and disengagement with and from the latch. An open lever is turnable on the casing and receives an operating force for releasing a locking state having the ratchet engaged with the latch. An internal operating-force inputting device transmits to the open lever a door opening operation force depending on the door opening operation within the vehicle. A locked-state switch-over device has an open link connected at one end to the open lever and switches over to an unlocked state to operate the ratchet from the engaged position to the disengaged position in response to the open lever turning, and a locked state inhibiting the ratchet from going to the disengaged position, irrespective of the turning movement of the open lever. The open link extends along a plane perpendicular to a lengthwise direction of the ingress passage and, is disposed sideways of the bulged portion on an opposite side from an inlet of the passage. The space occupied by the door lock device in the direction to avoid interference with a glass sash, along the thickness of a door can be small, and the door internal structure and thickness can be designed as desired.

摘要： In a magnetic recording system including magnetic recording media, a rotation driving unit for driving these magnetic recording media, read/write magnetic heads, driving apparatus for driving these read/write magnetic heads, and a read/write signal processing apparatus, a reading portion of the respective magnetic heads is arranged by a magnetoresistive head. The magnetic recording media are constructed of multi-layered magnetic media having a plurality of magnetic layers fabricated directly, or via underlayers on a non-magnetic disk substrate, and of non-magnetic intermediate layers arranged among these non-magnetic layers. Furthermore, one coercivity which is measured by applying a magnetic field along a circumferential direction of the magnetic recording media, is selected to be larger than the other coercivity which is measured by applying a magnetic field along a radial direction of the magnetic recording media, so that a higher signal-to-noise ratio is achieved, as compared with that of the conventional magnetic recording system. Since the thickness of the non-magnetic intermediate layers is smaller than or equal to 5 nm, and also the total layer is smaller than or equal to 5 nm, and also the total layer number of the plural magnetic layers is selected to be odd, better characteristics can be achieved. Accordingly, since the MTBF (Mean Time Before Failure) is longer than or equal to 0.15 million hours with high recording density, and the disk substrate and the magnetic head sliders can be mounted at high packaging density, a compact and high-capacity magnetic recording system can be obtained.

摘要： A magnetic recording medium and magnetic recording apparatus which can provide a high output level and a low noise level are disclosed. A magnetic recording medium includes a multilayer structure of magnetic alloy thin films containing Co, and at least one paramagnetic intermediate region or oxygen-rich region disposed between the magnetic layers. The intermediate region reduces the magnetic interaction between the magnetic layers without the degradation of crystallinity of the magnetic layers. As a result, a magnetic recording medium having such a structure shows low noise performance and a high recording density.
