Abstract: PURPOSE:To obtain an interlayer film having a good flatness without generating a crack by a method wherein prior to a process, in which a coat insulating film is subjected to baking and is vitrified, the insulating film is etched back until the thickness of the insulating film which stays in recessed parts becomes a thickness, in which no crack is generated in the insulating film even if the insulating film is vitrified. CONSTITUTION:An inorganic coat insulating film 15a containing silanol, or the like as its main component is formed on a lower silicon oxide film 15a by a spin coating method, for example, in such a way that recessed parts 20 formed in the surface of the film 15a are filled with the film 15b. After that, a baking is performed for several minutes at temperatures of 100 to 300 deg.C and solvents, such as alcohol and the like, are evaporated from the film 15b. Then, the film 15b is subjected to entire surface etchback by an isotropic dry ethcing method, in which the mixed gas of Freon, for example, and oxygen is used as reaction gas. After that, a baking is performed at a temperature of 400 deg.C or higher, for example, for stabilizing the film 15b by vitrifying. At this time, as the thickness t2 of the film 15b in the recessed parts 20 is 0.5mum or thinner, no crack is generated in the film 15b.

Title: Automatic tracking method for magneto-optical disk
Inventor: AJIKI SEIICHI
IPC: G11B11/105
Filed: 1989-12-29
Abstract: PURPOSE:To perform accurate tracking control by detecting movement of the condensed form of a luminous flux in the direction orthogonal to the luminous flux in a preliminarily determined fixed position by an optical system and controlling the position deviation from a reproduced information signal of a magneto-optical disk in accordance with this movement position by the intensity of reception light due to the angle of polarization. CONSTITUTION:Two luminous fluxes of the p-polarized component and the s-polarized component are separated from each other by a second optical system and are photoelectrically converted by two-divided or four-divided photodetectors 10 and 13, and only different phase components are detected as a difference signal from respective output signals by subtractors 33, 38, 42, and 44 and a divider 45. That is, reflected light from the recording layer of a magneto-optical disk 15 is divided to p-polarized component and s-polarized components, and movement due to luminous fluxes of respective polarized components is recognized as the change of the intensity of reception light based on the angle of polarization by preliminarily determined fixed two- divided or four-divided photodetectors 10 and 13. Thus, accurate tracking control free from the power change of incident light, the change of light reflectivity, and the characteristic change of the recording layer is performed.
