Title: Optical information recording and reproducing device
IPC: G11B11/10
Filed: 1992-03-31
Abstract: PURPOSE:To stabilize the magnetic wall position of an information magnetic domain and enable high-density recording by determining the driving current of a light source according to the detection result obtained by a detecting means which detects the compensation temperature of a recording medium. CONSTITUTION:A laser output control circuit 24 reads a driving signal corresponding to a light output Ir out of a data table, reads a driving signal corresponding to the temperature difference between magnetic wall formation temperature Tth and compensation temperature Tcomp out of a previously stored data table, and adds the difference to the driving signal corresponding to Ir to generate a laser driving signal corresponding to the high light intensity of recording operation. Then the relation between the highest arrival temperature Tm and magnetic wall formation temperature Tth can be controlled by varying the value of the driving current. For the purpose, the data table where Tm-Tth can variously be specified is previously stored in the memory in the laser output control circuit 24 and then pen tip recording which is more stable than before can be performed, so that higher-density recording can be carried out.

Title: Vacuum vapor deposition method of al
Inventor: YOSHIDA YASUYUKI
IPC: C23C14/24
Filed: 1988-04-28
Abstract: PURPOSE:To carry out the vacuum vapor deposition of Al with superior workability, productivity, and economical efficiency and also to prolong the service life of a graphite-type vessel by providing a specific composition consisting of Al and Zr or Al and Ti to a molten bath in the above vessel. CONSTITUTION:In a method for performing the vacuum vapor deposition of Al by using a graphite-type crucible, a molten bath in the above crucible has a composition consisting of, by atom, 20-65% Al and 80-35% Zr or 30-70% Al and 70-30% Ti. The molten bath with the above composition is free from phenomena similar to superfluidity by the presence of Zr or Ti, and, accordingly, this molten bath is minimal in infiltration into pores existing in the graphite and reduced in sticking power to the internal surface of the crucible. As a result, the occurrence of fracture of crucible due to molten bath can be prevented. Further, at the time of vacuum vapor deposition by using the above molten bath, Al is preferentially evaporated and the influence of Zr or Ti on a vapor-deposited film can be practically removed.
