<P>PROBLEM TO BE SOLVED: To provide an optical disk player which appropriately superimposes a high frequency current in a simple configuration. <P>SOLUTION: The DSP32 of a DVD player 100 has a DC current supply section 321 to supply an LD11 with a DC current equal to the reference current I0 of a preset current value, a high frequency current supply section 322 to superimpose a preset high frequency current of a predetermined amplitude Iw on the DC current to be supplied to the LD11 by the supply section 321, and a correction section 324 to make the DC current supply section 321 decrease the reference current I0 by the amount of the preset correction current value ΔI0 when superimposing a high frequency current by the high frequency current supply section 322. <P>COPYRIGHT: (C)2009,JPO&INPIT |
