Title: Magnetic tape apparatus with ideal correcting function of equalizer and ideal correcting method for equalizer of magnetic tape apparatus
Inventor: MIYAKO TAKASHI
IPC: G11B5/035
Filed: 1992-10-08
Abstract: PURPOSE:To optimize characteristics by providing a characteristic variable equalizer circuit and correcting characteristics on the basis of the comparing result of waveforms in a waveform comparison circuit. CONSTITUTION:A waveform comparison circuit 9 stores read signals into an internal register after sampling the signals. The waveform of signals stored in the register is compared with an ideal waveform in a ROM 12 by a waveform comparing part 11, thereby obtaining a correcting factor and a correcting amount. A characteristic variable equalizer circuit 10 of a differential/equalizer circuit 7 is hence set. Accordingly, the data read while the resolution is low increases a Q value by increasing a value set in the circuit 10, while the data read with the high resolution decreases the Q value. Therefore, when the data is scanned several times and the similar trials are made repeatedly, the difference from the data of the ideal waveform is made small and the equalizer is optimized.

Title: Focus control signal detecting system of optical disk device
Inventor: ARAI SHIGERU
IPC: G11B7/09
Filed: 1984-12-20
Abstract: PURPOSE:To obtain a system suitable to reduce weight easy to adjust optical system and able to obtain highly stable focus controlling signals by utilizing characteristic of differential output of a split type light detector that changes linearly corresponding to defocus distance of light beam spot. CONSTITUTION:The center axis of reflected luminous flux of diameter phi that enters parallel to the optic axis t of a light receiving lens 9 is shifted by necessary amount to the optic axis t, and when the diameter phi becomes large, overflowed part 19 from the edge of the light receiving lens 9 increases. Reflected luminous flux that passed through the light receiving lens 9 is converged and projected to a light detector 10'' of bisected type. In the figure of the bisected type light detector 10'', (u) and (v) denote output of left and right respectively. Position of the light detector 10'' is adjusted precisely and fixed on a plane perpendicular to the optic axis to make the value of differential output (u-v) zero when the position of an objective lens 6 is at focused position Lo. Then, v becomes larger than u by the effect of vignetting of the reflected luminous flux by the edge of the light receiving lens 9, and diameter phi of the reflected luminous flux becomes small. However, the center deviates to the left side and u becomes larger than v.

Abstract: PURPOSE:To realize a compact signal processor and to make the laying of an optical-transmission line easier by installing exciting members at different positions in the longitudinal direction of the optical-transmission line, and setting a light emitting member and a light receiving member in one housing. CONSTITUTION:Oscillation exciting members 14 are installed at the different positions in the longitudinal direction of an optical-transmission route 3, and a light emitting member and a light receiving member are installed in one housing 12. As a result, an optical-transmission route 3 is oscillated at the exciting members 14, and the frequency component responding to the oscillation frequency of the exciting members 14 is presented in the detecting signal owing to the microbending generated in the optical-transmission route 3.
