摘要： Method and apparatus for a disk texturing operation in which laser pulses are successively bombarded against a delimited surface area on the face of a rotating disk, from an optical laser pulse irradiating means which is put in movement in a radial direction relative to the disk to provide a textured zone of a predetermined width on the disk. A pulsed laser beam from a laser light source is adjusted to an optimum power level for an aimed bump diameter. The laser beam is then transformed into an annular beam of a collimated light flux having specified inner and outer diameters, and the resulting laser pulses are successively bombarded on the texturing zone through an objective optical system condensing said laser pulses into a specified spot diameter thereby to form minute bumps of predetermined shape and diameter uniformly on the surface of the disk.

摘要： Method and apparatus for registering and bonding upper and lower substrate plates together through a sealer material and in such a way as to form a gap of a predetermined width between the two substrate plates. Registered substrate plates are provisionally pressed to form a joined substrate assembly, which is then pressed under heated conditions at a hot press station, thereby compressing the sealer material into a flattened form and at the same time thermally hardening the sealer material to form a predetermined gap space between the two substrate plates. In order to correct positional deviations which occur to the upper and lower substrate plates in the course of the hot pressing, on the basis detected positional deviations of upper and lower substrate plates of a hot-pressed substrate assembly, upper and lower substrates are set in offset positions instead of aligned positions when registering them at the provisional press station to cancel predicted positional deviations at the hot press station.
