Title: Magneto-optical recording medium
Inventor: NAITO KAZUNORI
IPC: G11B11/105
Filed: 1989-09-20
Abstract: PURPOSE:To improve recording sensitivity and read-out power by forming a heat-radiating layer between dielectric layers formed on a magneto-optical recording layer, with using such a material having higher thermal conductivity than the magneto-optical recording layer. CONSTITUTION:On the opposite side of the recording layer 3 to the substrate 1, dielectric layers 4, 6 are formed with the heat-radiating layer 5 interposed. By properly selecting and combining the structure of each layer and Curie temp. of the recording film, the minimum recording power can be increased while reduction of the optimum recording power can be realized. The heat- radiating layer 5 consists of such a material having higher thermal conductivity than the recording layer 3, for example, such as aluminum (Al) and copper (Cu). By inserting the heat-radiating layer 5 between the dielectric layers 4, 6 which are generally provided for protective effect, this means that the dielec tric layer 6 covers the heat-radiating layer 5. Thereby, the obtd. magneto-optical recording medium has high sensitivity stable against deterioration of signals due to read-out power. Moreover, the obtd. medium is suitable for high-speed rotation, which improves reliability of the disk.

IPC: G06K9/68
Filed: 1989-09-20
Abstract: PURPOSE:To improve the matching rate and read accuracy of word matching processing by sorting and storing candidate characters for internal data which is outputted when an optical character reads a character by differences and further providing a candidate addition dictionary. CONSTITUTION:A candidate character addition processing part 1C looks up a candidate character addition dictionary 1D with a candidate character in a candidate character sorting register 18 to know a candidate character to be added and a difference extent calculation constant corresponding to the candidate, thereby calculating the extent of the difference. The difference extent calculation uses an optional function whose arguments are the extent of the difference of the candidate character, the order of the candidate character, and difference extent calculation constant. The additional candidate is applied to the register 18 according to the extent of the difference as to the candidate present in the register 18 before the start of candidate character addition processing. A candidate character output processing part 1B outputs a candidate other than the final candidate outputted by a final decision part 19 in the sorting order in the register 18. Therefore, the candidate character is added by the candidate character addition processing, so the percentage of the content of the correct candidate is improved.
