    摘要： A magnetic disk drive which is to be used for recording and/or reproducing information, and a bearing assembly for use in the same magnetic disk drive. The bearing assembly includes two bearings of different diameters, of which a small-diameter bearing is arranged within an inner periphery of a large-diameter bearing. The two bearings are joined by means of bearing coupling members for connecting respectively inner rings and outer rings of the bearings. The small-diameter bearing is arranged within the inner periphery of the large-diameter bearing, and therefore a height of the bearing assembly can be made thinner to about one and a half times a height of a single bearing. It is therefore possible to make the magnetic disk drive smaller and thinner by employing this bearing assembly.

    摘要： A magnetic disk unit is provided which can protect internal mechanisms from external force. A cover 11 covers the outer periphery of a base 12 which supports a spindle mechanism 2 and a head positioning mechanism 5. The cover 11 is connected to the base 12 elastically to reduce the possibility that the external force directly acts on the base and to assure that the external force acting on the cover is transmitted to the base via a cushioning material, whereby the spindle mechanism and the head positioning mechanism are protected from the external force.

    摘要： A measuring circuit system in a magnetic field measuring apparatus of the invention has an amplifier and a band-pass filter connected in sequence on an output terminal side of the TMR element, the band-pass filter is a narrow-range band-pass filter such that a peak pass frequency of the filter that is a center is a basic frequency selected from a range of 10 to 40 GHz and a band width centered around the basic frequency is a narrow range of ±0.5 to ±4 GHz; and with the measuring circuit system, an SIN ratio (SNR) of 3 dB or greater is obtained, the SNR being defined by a ratio of an amplitude S of a high-frequency generated signal induced by the TMR element to a total noise N that is a sum of a head noise generated by the TMR element and a circuit noise generated by the amplifier. With such a configuration, an in-plane high-frequency magnetic field generated by a microwave-assisted magnetic head is reliably and precisely measured.
