Title: Optical disk device
Inventor: SATO SHINICHI
IPC: G11B7/125
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To set a value M so as to prevent the advance of the deterioration of a laser diode by setting an optical recording power value M when a β value first obtained by a double speed is within a specified range during power correction and performing correction again by reducing a rotational linear speed to a constant speed when the β value is not within the range. SOLUTION: The rotational linear speed of an optical disk 1 is first set to a double speed and data is recorded in the test area of a power calibration area(PCA) by the recording power values of a plurality of levels. Then, the peak value A1 and the bottom value A2 of the reproducing signal of the recording data are detected and a β value is calculated based on (A1+A2)/(A1-A2)=β. A center value 4% is set as an optimal recording power M when a β value is 0 to 8% and when the β value is not within this range, the rotational linear speed is reduced to one speed and then a βvalue is similarly obtained again so as to set a value M. Thus, a value M for preventing the advance of the deterioration of a laser diode is set and a time for its setting processing is shortened.

Filed: 1993-01-21
Abstract: PURPOSE:To exactly position by posessing a larger data run length than that allowable in at least one of the data sequence included in plural data sequences. CONSTITUTION:At the time when an input demend signal is received through a line 18 in the course of operation, a pulse generator 20 supplies one pulse to a recording device 26.

IPC: H02J3/12
Filed: 1994-01-31
Abstract: PURPOSE:To detect a reactive current at high speed by detecting the effective current of a load temporarily and subtracting the effective current from a load current thereby detecting the reactive current. CONSTITUTION:An effective power generating circuit 23 generates an effective power P from a load current IL and a load voltage VL detected, respectively, through a current transformer 6 and a potential transformer 7. An effective current generating circuit 24 generates an effective current Ip based on an output from the effective power generating circuit 23.
