IPC: G11B11/10
Filed: 1989-09-08
Abstract: PURPOSE:To improve the ultrahigh-density recording, i.e. the density in the transverse direction of tracks together with the density in the line direction and to improve reproducing S/N by obtaining a reproduced output by using a magneto-optical recording medium having a specific constitution and subjecting only the reproducing magnetic layer to magnetization inversion at the time of reproducing. CONSTITUTION:The magneto-optical recording medium 5 which has the reproducing magnetic layer 1, a magnetic recording layer 2, and transparent dielectric layers 31 and 32 and reflective layer 4 is constituted to have the sufficiently small reproduced output RXthetak (R is a reflectivity; thetak is a Kerr rotating angle) at the temp. Tth or bellow at which the reproducing magnetic layer 1 makes magnetization inversion is constitut ed. Only the reproducing magnetic layer 1 is subjected to the magnetization inversion by using such recording medium and the reproducing magnetic layer is irradiated with reading out light to obtain the reproduced output by the Kerr rotating angle. The magnetization inversion of the reproducing magnetic layer is executed by maintaining only the desired reproducing part at the temp. Tth or above, by which the reproduced output RXthetak is made sufficiently small at the temp. Tth or below. The high C/N is thereby obtd. and the crosstalks between the tracks are effectively averted. The higher density is thus obtd. even in the transverse direction of the tracks.

Abstract: PURPOSE:To provide a combustion device having a quite low variation in a value of CO/CO2 as a time is elapsed by a method wherein a wall member forming a combustion chamber, in particular a part enclosing a combustion flame is composed of substance not acting as oxidizing catalyst. CONSTITUTION:Polycrystal line silicon SiO2 or silicon nitride films 5b and 6b are formed only on each of the surfaces opposing to combustion flames of an inner flame cylinder 5 and an outer flame cylinder 6 made of metal having several air holes 11 and under a process of CVD (chemical vacuum deposition). That is, compound containing substance to be generated is supplied together with carrier gas and some chemical reactions such as a pyrolysis, oxidation and reduction or the like are carried out on a substrate to deposit a target substance. A film thus obtained is quite fine and its thickness is quite thin to show a value of several microns and so its thickness can be controlled freely. This is applied to all the surfaces facing to the flame such as a flame plate 12 and it may also be applied to such a portion as showing a hot temperature or a portion where an excessive oxidation is found. Applying of substance not acting as an oxidation catalyst to a portion enclosing a combustion flame eliminates almost all of a time deterioration of a value of CO/CO2 and so it may be used for a long period of time under its complete condition without deteriorating its performance.
