IPC: G11B7/085
Filed: 1992-06-05
Abstract: PURPOSE:To eliminate influence of a flaw of a disk, an ID, etc., by varying a peak value of a jump pulse according to a control signal of a circuit for controlling excessive jump/insufficient jump of a track, converting the pulse, and outputting it. CONSTITUTION:A judging circuit 3 detects a tracking error signal S4 when a previous jumping by a jump pulse S7 is finished, judges whether a track is excessively jumped or insufficiently jumped, and outputs a control signal S5. A voltage varying circuit 4 varies a peak value of the pulse according to the signal S5, and outputs a signal S6. A track jump generator 5 converts the signal S6 into a jump pulse S7 of a predetermined time, and outputs it. With this configuration, a tracking error signal of a flaw, etc., of a disk during jumping is not detected, the pulse S7 is output for a predetermined time to jump the track, and hence influence of the flaw of the disk, an ID, etc., can be eliminated.

Abstract: PURPOSE: To improve electrolytic polishing in efficiency by covering the cavity to be finished with an elastic substance and moving the abrasive-containing working fluid sealed in the cavity in order to allow the abrasive to remove the oxide film on the surface being finished.  
     CONSTITUTION: An object 2 to be worked is secured on a table 1. An elastic substance 4 is arranged so as to cover the cavity to be worked, and closely secured by a fixing member 6. The sealed cavity is filled with working fluid containing abrasive supplied from a working fluid regulating tank 1 by a pump 12 through a supply pipe 9 having a check valve 11 and a supply passage 7. Then a surface 5 is electrolytically polished by using a flexible electrode as a cathode and the object 2 as an anode. On doing this, the reciprocating motion of a pressure substance 19 causes the elastic substance 4 to be pressed downwards, and consequently the working fluid cyclically moves in the cavity. The movement permits the oxide film to be removed and exhausted through an exhaust passage 8.
