Abstract: A control circuit is provided for a vibration-type actuator that generates a vibration wave in a vibrating member by applying an alternating voltage, and relatively rotates a moving member contacting protrusions of the vibrating member. The control circuit includes a feedback control circuit and a repetitive compensator. The feedback control circuit subjects the vibration-type actuator to feedback control based on a deviation between a relative speed between the moving member and the vibrating member and a command speed or a deviation between a relative position between the moving member and the vibrating member and a command position. The repetitive compensator provides a repetitive period that is set to T/(an integral multiple of fs), where T is a period of rotation of the moving member, and fs is a spatial frequency of a speed deviation based on a contact area distribution between the protrusions and the moving member.

Abstract: A method of reproducing multilevel information using a light spot. The multilevel information is recorded by defining virtual cells at regular intervals on tracks of an optical information recording medium and varying sizes of information pits in the cells. The method includes the steps of obtaining cell boundary values, each of the cell boundary values being obtained by performing sampling when the center of the light spot reaches a boundary between adjacent cells, calculating cell boundary value metrics on the basis of the cell boundary values and prestored reference values for the cell boundary values, calculating path metrics on the basis of the cell boundary value metrics, selecting a path metric having a minimum value of the path metrics, and reproducing the multilevel information on the basis of the path metric having the minimum value of the path metrics.

Abstract: In a method of reproducing multilevel information, cell-boundary values are obtained. Each of the cell-boundary values is obtained when the center of a light spot comes at a boundary between adjacent cells. Then, on the basis of the cell-boundary values and prestored reference values for the cell-boundary value, cell-boundary-value metrics are calculated. Furthermore, on the basis of the cell-boundary-value metrics, path metrics are calculated.

Abstract: In three consecutive cells consisting of a preceding cell, a center cell, and a subsequent cell, a possible change rate of the amplitude of a reproduced signal for the center cell with respect to the sum of the multiple values of the preceding and subsequent cells is obtained in advance. Then, for reproduction, the sum of the multiple values of the adjacent preceding and subsequent cells is obtained with respect to each cell. The amplitude of the reproduced signal obtained at the center cell is corrected to be closer to a reference value on the basis of the obtained change rate and sum.
