Title: Optical recording medium
Inventor: AOI TOSHIKI
IPC: G11B7/24035
Filed: 1989-03-31
Abstract: PURPOSE:To obtain an optical recording medium possible to record, capable of performing good reproduction, easy to prepare, having high durability and low in cost by increasing the refractive index of the intermediate layer constituting the optical recording medium by the irradiation with recording light. CONSTITUTION:When an optical recording medium is irradiated with recording light on the side of the substrate thereof, an absorbing layer absorbs light to generate heat and the refractive index of an intermediate layer is increased by said heat. At this time, one or more pit is formed to either one of the substrate, the absorbing layer and the intermediate layer according to circumstances. By these changes, the multipath reflection condition in the medium is changed and the reflectivity of reproducing light in the recording light irradiated part, that is, a recording part is lowered. In this case, when the refractive index (n) and extinction coefficient (k) of the absorbing layer, the refractive indice (n) and extinction coefficients (k) of the intermediate layer before and after the irradiation with recording light and the thicknesses of both layers are set to predetermined values, the reflectivity of reproducing light of 6.0% or more is obtained in a non-recording part and the reflectivity of reproducing light of the recording part is lowered to 40% or less of that of the non-recording part and reproduction due to a CD player can be performed.

Abstract: PURPOSE:To detect an optical reception level, by providing a logarithmic amplifier outputting a voltage proportional to a logarithm which is a difference between the breakdown voltage of an avalanche photodiode (APD) and a bias voltage. CONSTITUTION:An optical signal is photoelectrically converted and multiplied for electrons at an APD1 and a voltage drop is produced across a resistor 2.
