Title: Magnetic disk medium and magnetic disk device
Inventor: TAKI MITSUHIRO
IPC: G11B5/82
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To improve the splashing characteristics of a lubricating film of a zone texture magnetic disk imparted roughness for preventing adsorption only to CSS zone. SOLUTION: Since this magnetic disk has texture grooves (2) on the outermost periphery, splashed lubricants are trapped in these grooves. Usually, the outermost periphery is a standby cylinder not subjected to reading and writing of data with the magnetic disk device and, therefore, the time a head exists in this trap groove part is longer than with the other part. At the time the head stands by on the outermost periphery, the lubricants are transferred to the heads and this cylinder is replenished with the transferred lubricants at the time the head accesses the other cylinder.

Title: Method and device for correcting interchannel dispersion of solid-state image pickup element
Inventor: DAIHO MASAHIRO
IPC: H04N5/341
Filed: 1988-07-12
Abstract: PURPOSE:To correct the interchannel dispersion of a solid-state image pickup element with good precision automatically by giving feedback to a signal mixing means toward a direction to reduce the dispersion of the amplitude of a moire component contained in a video signal. CONSTITUTION:The video signal A to be regenerated by a sampling circuit 7 and the video signal B to be regenerated by the sampling circuit 8 are different from each other in their phases by 180 degrees. The video signals A, B are mixed by a signal mixing circuit 9 alternately at every one picture element period, and are outputted to a buffer circuit 10. Here, if the amplitude of the signal A is different from the amplitude of the signal B, the moire component of frequency fSB is generated in the output signal C of the buffer circuit 10. Next, only the sideband wave component of the frequency fSB is extracted by, for instance, a moire detection circuit 11 having the pass band of fSB. Since the amplitude of the output signal D of this detection circuit 11 is the component proportional to the difference of the amplitudes of the signals A and B, the feedback is given to an amplification circuit 6 toward the direction in which this difference becomes zero in order to correct the interchannel dispersion of the amplitude.
