Title: Drop-out detecting circuit
Inventor: ABE SHOZO
IPC: G11B20/02
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a detecting circuit whereby drop-out is compensated regardless of the size of the amplitude of a reproduction RF signal by providing a comparator(COMP) where the synthetic voltage of the voltage of a rectifying circuit with a long time constant with a D.C. reference voltage and the voltage of the rectifying circuit with a short time constant are inputted. SOLUTION: The reproduction RF signal from a recording medium is amplified and inputted to the two rectifying circuits with different time constants. In the rectifying circuit D2 with the long time constant, the D.C. reference voltage Vref is synthesized with a rectifying voltage via a resistor R4 so as to generate a synthetic voltage VTh. In the rectifying circuit D1 with the short time constant, the rectifying voltage V1 is generated. The both voltages are inputted to a comparator(COMP). A drop-out detecting signal(DOS) outputted from COMP, DOS is normally outputted when he amplitude of the RF signal is large. When amplitude is small, the synthetic voltage VTh is elevated, compensated to output the DOS.

Abstract: PURPOSE:To make lens effect, that refracts incident light from a passivation step into a transfer side, smaller by farming a two-layer-structure passivation film, consisting of the first film containing hydrogen and the second film whose refractivity is lower than the first film, to reduce boundary level. CONSTITUTION:An Al film 22 is covered with a P-SiO film 25, or a light-shield film, and a P-SiN film 24 is formed on the film 25, so that these P-SiN film 24 and P-SiO film 25 form a two-layer-structure passivation film. The hydrogen in the P-SiN film 24 reaches the boundary between an Si substrate 11 and an SiO film 16 when thermal treatment is made after the film 24 is formed. The hydrogen terminates the unsaturated bond between Si and O at the boundary, to reduce boundary level. Incident light 27 an a step part 26 is made to refract into a vertical transfer register 14 side by the film 24, with the amount of light path deviation negligible. It refracts again, at the boundary between the films 24 and 25, in the direction opposite to the vertical transfer register 14, so the refraction of the light 27 is slight.
