Abstract: PROBLEM TO BE SOLVED: To cope with a high transfer rate of an optical disk drive unit. SOLUTION: A detecting signal of inputted laser beams is inputted to a ternary level detecting circuit 2 by a preamplifier 1, and ternary level signals corresponding to a peak power, erase power and cooling power of the laser beams are produced from the above detected signal. Then, the difference of this ternary level signal from the set value is obtained and the difference signal is inputted to a waveform generating circuit 8. In the waveform generating circuit 8, the adding/non-adding operations of the difference signal are executed in accordance with data for recording, and a laser control signal for data recording is produced and outputted to a laser driver. Also, when the data are erased, the laser control signal for data erase is produced in the waveform generating circuit 8 by using an output of the ternary level detecting circuit 2, but when the data are reproduced, the detected signal is inputted to the waveform generating circuit 8 through the route different from the ternary level detecting circuit 2 to produce the laser control signal for data reproduction.

Abstract: PROBLEM TO BE SOLVED: To solve a problem of a timing shift of pulses due to a difference in wire length and enable the emission of optical pulses of a shorter light emission time at a high transfer rate by reducing the number of wirings. SOLUTION: An emitter grounded circuit 18 having a single circuit analog signal input system converts a voltage signal J1 inputted from an input terminal 18a into a current signal, and is so structured that a signal output from a high frequency oscillator circuit 20 is added to the current signal of the emitter grounded circuit 18 at the time of regeneration. A signal on the J1 side is boosted for a higher area within a band of a transistor Q6 while the deterioration of the output signal of the high frequency oscillator circuit 20 is kept as small as possible by means of a base grounded circuit of the transistor Q6. A current switching circuit 16 cuts off or passes a current inputted into a current mirror circuit 12 in a next stage to cut off or output an output current of the current mirror circuit 12.
