Title: Disk-shaped optical information recording medium and its production
Inventor: IINO TETSUYA
IPC: G11B7/24062
Filed: 1988-05-26
Abstract: PURPOSE:To obtain the disk-shaped optical information recording medium which can form good pits over the entire surface of the disk by using a material having a high thermal conductivity as a reflecting film in the part where a line speed is low and using a reflecting film having a low thermal conductivity in the part where the line speed is low. CONSTITUTION:A protective layer 23 is deposited on a substrate 22 formed of polycarbonate or acrylic resin, etc., and the material such as Sb2Te3-GeTe having a high crystallization rate is deposited as a recording layer 24 thereon. Further, a protective layer 25 is deposited thereon. The material such as Au, Ag, Cu or Al having the high thermal conductivity is deposited to the sound region in the inner circumferential part as the reflecting layer 26 on the protective layer 25 and the material such as Ni, Cr or Pt having the low thermal conductivity is deposited on the video region in the outer circumferential part. The heat required for recording is, therefore, more easily diffused in the region where the line speed is low. Rapid cooling is attained therein and the recrystallization of the amorphous recording pits is prevented. The diffusion of the heat is low in the region where the line speed is low and, therefore, the recording with relatively small power is possible.

Title: Automatic equalization method
Inventor: TSUCHINAGA HIROYUKI
IPC: G11B7/14
Filed: 1991-05-30
Abstract: PURPOSE:To provide system for automatically equalizing regenerative signals from a plurality of heads by the use of a common waveform equalization circuit and to provide an automatic equalization system being applicable even if parts without signals are generated in the regenerative signals. CONSTITUTION:The input stage of an automatic equalizer 7 is provided with an analog multiplexer 8 and the initial values of equalizing conditions are read out from a memory 10 so that regenerative signals from optical heads 3, 3' are selectively subjected to automatic equalization. The automatic equalization is stopped at the time of the access of an optical head or at the time of a track jump or when the part is judged to be without signal by a detecting circuit for parts without signals. Thus, a plurality of heads can have a waveform equalizer for equalizing regenerative signals for common use and it is easy to miniaturize an apparatus and to reduce its cost. Also, even if parts without signals are generated in the regenerative signals and further a recording medium with different characteristics is used, the automatic equalization is possible without any regulation.
