摘要： An information playback apparatus includes a first FIR filter, ideal signal generator, weighted equalization error calculator, and coefficient calculator. The first FIR filter generates an equalized waveform by equalizing, to a partial response waveform, a playback data string obtained by playing back a recorded signal recorded on an information recording medium. The ideal signal generator generates a target waveform serving as an equalization target. The weighted equalization error calculator calculates a data string by performing convolution computation for an equalization error which is a difference between the equalized waveform and the target waveform, on the basis of one of the playback data string and the equalized waveform input from the first FIR filter and the target waveform input from the ideal signal generator. The coefficient calculator calculates a tap coefficient for the first FIR filter on the basis of the data string input from the weighted equalization error calculator, and outputs the tap coefficient to the first FIR filter. An information playback method is also disclosed.

摘要： There is disclosed an optical information recording medium having phase-change recording films whose the transmittance can be made substantially uniform irrespective of the presence or absence of recording. There are also disclosed methods for recording, reading, and erasing information well at a high density on such a medium.

A transparent upper protective film is formed on the phase-change recording film to protect the phase-change recording film mainly against thermal deformation during recording and erasing of information. A transparent lower protective film is formed under the phase-change recording film to protect the phase-change recording film mainly against thermal deformation during recording and erasing of information. A foundation interference film is formed under the transparent lower protective film to adjust the transmittance of the phase-change recording film for the laser light.

摘要： An optical information recording medium includes a transparent substrate, a first dielectric layer, a recording layer, a second dielectric layer, a reflecting layer, and a third dielectric layer. The substrate constitutes an optical disk for performing a mark edge recording operation. The first dielectric layer is formed on the substrate. The recording layer is formed on the first dielectric layer and is irradiated with a laser beam to undergo a reversible phase change between a crystalline state and an amorphous state, thereby recording and erasing information. The recorded information is reproduced by detecting a change in optical characteristics accompanying a phase change of the recording layer. The second dielectric layer is formed on the recording layer. The first and second dielectric layers protect the recording layer. The reflecting layer is formed on the second dielectric layer and has a predetermined transmittance. The third dielectric layer is formed on the reflecting layer and has a thickness set to control a relationship between an absorbance Ac of the recording layer in the crystalline state and an absorbance Aa in the amorphous state according to Ac>Aa. The dielectric layer is made of a dielectric material having a refractive index n larger than 1.5.
