Abstract: A speaker includes a ring-shaped vibrating member fixed to an internal support body at an internal peripheral edge, and a bobbin attached to an external peripheral edge thereof. A voice coil is attached to the bobbin and is located in a magnetic gap. A ring-shaped control member faces a front portion of the vibrating member, and a sound pass space is formed at an external peripheral side of the control member and at an internal peripheral side thereof. When listening to the speaker from a diagonal location, treble sound waves generated from the left side area are perturbed by the control member so as to prevent interference from sound waves generated from bilaterally separated areas, which prevents a decrease of treble sound pressure levels.

Abstract: Disclosed is a substrate attenuator circuit having a thin, long conductive pattern with a plurality of bends on a substrate, with heat generation per unit area reduced to a small amount even at a low attenuation level. A linear conductive pattern configured to have a plurality of bends on a substrate is provided with output terminals at n portions thereof. The conductive pattern has a larger line width at a first stage conductive pattern portion defined in a portion from an input terminal to m output terminals (m<n) than the line widths of the conductive pattern portions defined in the remaining portion, the m output terminals being disposed closer to the input terminal of the output terminals of the n portions. The first stage conductive pattern portion is thus increased in conductor area, and heat generation per unit area is reduced to a small amount even when only the first stage conductive pattern portion is used to obtain a low attenuation level.

Abstract: A servo write method for a hard-disk drive. The method includes generating, with an input of characteristics of a magnetic-recording head and a magnetic-recording disk which are incorporated into the hard-disk drive, a yield prediction model from a correlation between yields of the hard-disk drive, and characteristics of the magnetic-recording head and the magnetic-recording disk of the hard-disk drive in a process. The method also includes predicting a yield which is obtained when each magnetic-recording head is used as a position control head, selecting as the position control head a magnetic-recording head that has a highest predicted yield, and writing a servo signal.

Abstract: A speaker includes a magnet, a yoke, and a coil. A surface of the magnet opposed to the yoke includes a first magnetized surface at one side in the moving direction of the coil and a second magnetized surface at the other side in the moving direction of the coil. The two magnetized surfaces have the same magnetic polarity. A central surface between the first magnetized surface and the second magnetized surface is not magnetized or is magnetized more weakly than the first magnetized surface and the second magnetized surface. The single magnet of this structure forms the same magnetic force distribution as two separate magnets so that the speaker provides a superior linearity of driving force of the coil.

Abstract: A disk unit is capable of detecting a track, the track width of which deviates from a normal value, with high accuracy at high speed. A HDD includes a read head, a disk and defective-track detecting part. The disk has servo data including bursts A, B written thereon. The servo data is used to position the read head to a track center. The defective-track detecting part detects a defective track as below. The sum of the amplitude of bursts A and B, which have been read by the read head by one read operation, is divided by the amplitude of a burst C or D to obtain a compared value. If the compared value deviates from a criterion by a specified percentage or more, it is judged that the track width of a track is abnormal. Since bursts A through D are written without trimming, the size of bursts A through D in the track width direction are kept constant regardless of the track width. Accordingly, a gap G fluctuating in accordance with the track width is formed in the radial direction between bursts A and B.

A surface of the magnet opposed to the yoke includes a first magnetized surface at one side in the moving direction of the coil and a second magnetized surface at the other side in the moving direction of the coil. The two magnetized surfaces have the same magnetic polarity. A central surface between the first magnetized surface and the second magnetized surface is not magnetized or is magnetized more weakly than the first magnetized surface and the second magnetized surface. The single magnet of this structure forms the same magnetic force distribution as two separate magnets so that the speaker provides a superior linearity of driving force of the coil.
