Title: Tracking servo device
Inventor: NAKAJIMA YOSHIHIDE
IPC: G11B7/09
Filed: 1988-03-14
Abstract: PURPOSE:To improve the beam follow-up accuracy by dividing the level of a signal in accordance with the difference of levels between the 1st and 2nd pits of the servo signal read out of a recording medium as well as the level of said servo signal for acquisition of a tracking error signal. CONSTITUTION:A tracking error signal (A-C)-(B-C)/(A-C)+(B-C) is obtained by dividing the level of a signal in accordance with the difference between the signals A and B of the 1st and 2nd pits of a servo signal read out of a recording medium and the level C of the servo signal. Thus it is possible to obtain a tracking error signal regardless of the difference of sensitivity among the servo signal detecting systems of a mounted optical disk device, a fixed disk device, etc., and the difference of the level of the servo signal due to the reflectivity, etc., of the recording medium. As a result, the beam follow-up accuracy is improved.

IPC: H01S5/00
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To minimize the distance between a semiconductor laser and diffraction optical lens to the limit by placing the emitting position of a semiconductor laser-emitted light within a focal plane of this lens and reversing at least a part of diffracted light to return it to the end face of an active layer of the semiconductor laser. SOLUTION: A light 2 emitted from a semiconductor laser 1 is incident on a transmission type refractive optical lens 3 formed on the surface of a transparent base 4 to provide diffracted lights formed into collimated lights 6 by placing one end face of an active layer of the laser 1 at the focus of the lens 3. The lights 6 are partly reflected by a partial reflection film 5 to reverse the optical path 180 deg. and hence incident on the lens 3 again. The collimated light is incident on one end face of the active layer of the laser 1, disposed at the focus. Since the focus position of the lens 3 differs, depending on the wavelength, only the light of specified wavelength is incident on the active layer again, thus stabilizing the oscillation wavelength.

Abstract: PROBLEM TO BE SOLVED: To enable a low-voltage operation by amplifying the voltage of a bit line with a sense amplifier after pulse-driving a cell plate, and thereby removing influence from the threshold of a memory cell transistor. SOLUTION: Bit lines BL0 and /BL0 are precharged to a logical voltage 'L'. A word line WL0 is set for a logical voltage 'H', and so is a cell plate signal CP.

With an electric field propagated on both electrodes of the ferroelectric capacitor C00, C01; generated between the bit lines BL0 and /BL0 is an electric potential which is determined by the ferroelectric capacitor and the bit line capacity. In the potential difference between the two, the effect of the threshold of the memory cell transistor is cancelled, with the signal amplified so much. With the cell plate signal CP set for a logical voltage 'L', it is read out by a sense amplifier SA0.
