    摘要： A method of targeted corruption of user data in a shingled magnetic recording disk includes identifying user data on a Track_N targeted for corruption; identifying a readback centerline of the Track_N; identifying a readback centerline of an adjacent track to Track_N; acquiring user data of the adjacent track; and rewriting the user data of the adjacent track with an offset write centerline to overwrite magnetic material at the readback centerlines of both Track_N and the adjacent track.

    摘要： Embodiments in accordance with the present invention relate to improving error recovery process performance. A head slider in an embodiment of this invention includes a heater for adjusting a clearance between a head element section and a magnetic disk. During an error recovery process (ERP) for a reading error, if a particular environmental temperature is in a low-temperature region, a microprocessing unit (MPU) executes the ERP steps of increasing a heater power value of the heater (i.e., STEP X to STEP X+2), preferentially over the ERP steps of reducing the heater power (i.e., STEP X+3 to STEP X+5). In the low-temperature region, the possibility of error recovery in an earlier step can be raised by executing the heater power increasing ERP steps earlier than the heater power reducing ERP steps.

    摘要： A camera includes a motor, a first planetary gear which revolves on the basis of an output rotation of the motor, a second planetary gear which revolves on the basis of the output rotation of the motor, a first camera operating mechanism which engages with the first planetary gear by the revolution of the planetary gear caused by a rotation of the motor in a first direction, a second camera operating mechanism which engages with the second planetary gear by the revolution of the second planetary gear caused by the rotation of the motor in the first direction, and a selector for selectively preventing the revolution of either of the first and second planetary gears. The selector selectively permits the operation of either of the first and second camera operating mechanisms during the rotation of the motor in the first direction.

    摘要： A camera is provided with automatic focusing circuitry which is arranged to begin to operate to drive a focusing motor, in response to an operation performed on a shutter release button, to bring the motor to a stop upon detection of an in-focus state and to produce an in-focus signal. Photometric circuitry is arranged to begin to operate in response to the operation on the release button to obtain a photometric value by detecting the luminance of an object to be photographed, and to be capable of renewing the photometric value in response to a change in the luminance of the object. The photometric value is locked in response to the generation of the in-focus signal. Control circuitry means which controls the photometric apparatus in response to cancellation of the operation on the release button. The control circuitry unlocks the photometric value kept at the photometric apparatus and allows the photometric apparatus to operate to obtain another photometric value by detecting the luminance of the object once more within a predetermined period of time.

    摘要： A deflector for a cathode ray tube (called herein "CRT"), and more particularly a stator type deflector in which a plurality of slots for windings are formed in the inner surface of a tubular core and deflecting coils are positioned in these slots. Both convergence (spot) distortion and raster (pin cushion) distortion are small. The magnetic field distribution at the neck is a barrel type, and that at the screen is a pin cushion type. Both the horizontal and the vertical magnetic fields are obtained by adjusting the positioning of the winding slots formed in the inner surface of the tubular core for positioning the deflecting coils. This is accomplished by adjusting the angles of the plurality of winding slots formed in the inner surface of the tubular core which contain the deflecting coils.
