摘要:
An optical recording medium has a mask layer 4, an intermediate dielectric layer 5, a recording layer 6, and a reflective layer 8 on a transparent substrate 2. The recording layer 6 contains a recording material which changes its crystallographic structure upon exposure to recording light for recording information. The mask layer 4 contains a mask material which increases its light transmittance when melted and has a complex refractive index (n.sub.0 -ik.sub.0), of which the real part n.sub.0 drops by 1.0 or less and the imaginary part k.sub.0 drops by 0.25-1.0 when the mask material converts from a crystalline state to an amorphous or microcrystalline state. Signals can be reproduced from the medium with high C/N without resorting to reading light of shorter wavelength or an optical pickup objective lens having a larger numerical aperture and even when the linear velocity of the medium relative to recording and reproducing light is low.

A phase change type optical recording medium has a recording layer of a recording material containing elements A, B, and C wherein A is Ag and/or Au, B is Sb and/or Bi, and C is Te and/or Se. Information is recorded by directing a light beam to the recording layer to form recorded marks therein such that the recorded marks are amorphous or microcrystalline while an unrecorded portion of the recording layer remains crystalline, and the A concentration of the unrecorded portion is at least 0.5 atom % higher than the A concentration of the recorded marks. C/N and modulation factor are improved and such improvements are kept even after hot humid storage.

摘要:
The present invention provides an electrolytic capacitor manufacturing method capable of manufacturing an electrolytic capacitor having the PTC function as easy as possible. A main electrode layer in a cathode is formed so as to have the PTC function. Different from a conventional electrolytic capacitor manufacturing method of connecting a PTC thermistor to a capacitor element to give the PTC function to an electrolytic capacitor so that an electrolytic capacitor manufacturing process is complicated and the number of manufacturing processes is increased by the amount corresponding to the PTC thermistor connecting process, the process of connecting the PTC thermistor to the capacitor element is unnecessary. Consequently, complication of the electrolytic capacitor manufacturing process and increase in the number of manufacturing processes caused by the PTC thermistor connecting process can be prevented.
