Title: Optical information recording and reproducing device thereof
Inventor: YAMADA NOBORU
IPC: G11B7/125
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical information recording and reproducing device that suppresses jitters at the recording position of a recording mark. SOLUTION: The light optical intensity is pulse-modulated between a power level P1 and P2 , (P1 >P2 ), at a frequency f1 corresponding to an information signal. In a part where a recording mark is formed by the irradiation of the power level P1 , as a pulse line with the frequency f2 superposed that is higher than the frequency f1 and independent of the information signal, the laser power is emitted through modulation between the power level P1 and P0 (P2 >P0 ). In converting from P1 to P2 , it is passed through P0 , and the laser modulating means is controlled in a manner such that the pulse width corresponding to the frequency f2 is longest at the time immediately after the irradiation power is switched from P1 to P2 or vice versa, in accordance with the frequency f1 . Thus, overwriting with less jitters can be realized.

Title: Power amplifier
Inventor: MATSUMURA EIICHI
IPC: H03F3/30
Filed: 1981-03-20
Abstract: PURPOSE:To suppress harmonics generated at saturation, by adding an output drive limit circuit. CONSTITUTION:When a positive input signal is applied to a terminal (a), a current flowing to a transistor (TR)Q6 is decreased and the collector potential of a TRQ5 is increased. The potential at a bootstrap terminal (e) is further increased, because the potential of an output terminal (d) is increased with the conduction of TRs Q10 and Q11 and the potential increase is fed back to a terminal (e) with a bootstrap capacitor C4. Thus, a VCE of TRs Q5 and Q10 can drive a TRQ11 with a sufficient margin. The collector potential of the TRQ5 is increased and the output TRQ11 reaches the saturation, then a TRQ3 is conductive and the collector current of the TRQ5 by-passes to ground and the TRQ11 is not driven further. Thus, no steep output trailing is caused and generation of harmonics is less, because oversaturation is not made. In this case, since the terminal (e) is sufficiently higher in potential than the power supply voltage, a diode D1 is conductive and a bias voltage higher than the power supply voltage by the potential drop of a resistor R4 is given to the base of the TRQ3.
