Title: Auto-tracking device
Inventor: SHIMAYA KATSUHISA
IPC: G11B15/467
Filed: 1989-12-15
Abstract: PURPOSE:To perform accurate tracking control regardless of a low signal level by changing the relative position of a signal converting element to a recording track so that the control signal obtained by logarithmic compression of an envelop is maximum. CONSTITUTION:An inputted reproduced signal is converted to a DC signal corresponding to the envelope of the reproduced signal by a detecting circuit 6 and is logarithmically compressed by a logarithmic compressing means 9 and is inputted to a tracking control circuit 7. The control signal subjected to the logarithmic compression processing has the same change rate as the reproduced signal level independently of the reproduced signal level, and as the result, tracking control is performed for the wide input signal level range.

Title: Light transmitter
Inventor: INOUE YASUSHI
IPC: H04B10/516
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a light transmitter with less transmission deterioration due to frequency chirp by widening a drive modulation band to an electric field absorption type optical modulator than a transmitted signal speed. SOLUTION: A semiconductor electric field absorption type optical modulator (hereinafter called as EA modulator) 12 intensity modulates a beam emitted from a semiconductor laser 10 based on a signal outputted from a pulse pattern generator 14. Since a phase of an output beam from the EA modulator 12 is changed according to an applied voltage to the EA modulator, the chirp occurs in a time area when the applied voltage to the EA modulator 12 is changed. When a drive signal band is wide, the applied voltage is changed from an on (off) level to an off (on) level in a short time. Thus, the EA modulator 12 is driven by a drive circuit of a band wider than the signal speed.  That is, when the unit of the signal speed is defined bit/sec, and the unit of the modulation band is defined GHz, a numerical value representing the signal speed is made larger than the numerical value representing the modulation band.
