Title: Optical recording medium
Inventor: NAGATAKI YOSHIYUKI
IPC: G11B7/24035
Filed: 2000-01-12
Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium with improved recording/ reproducing characteristics at the starting position in an information recording area. SOLUTION: This optical recording medium has a recording layer containing a dyestuff on a substrate. The innermost peripheral position of the recording layer is formed on the inside of the innermost peripheral position of the information recording area where information is recorded by 2 mm or larger, more preferably 3 mm or larger. Thereby, the recording/reproducing characteristics are enhanced at the starting part of the information recording area since the inhomogeneous part of the dyestuff caused at the application starting position is not included in the information recording area when the dyestuff constituting the recording layer is applied, for example, by the spin coat method.

Title: Via-hole processing method and its apparatus
Inventor: KOSEKI RYOJI
IPC: B23K26/00
Filed: 2000-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a via-hole processing method which can process a via-hole with better accuracy and its apparatus. SOLUTION: A pulsed laser beam L1 for processing is irradiated to a first layer 5A of a complex material 5 so that a via-hole 5V is made. A laser beam L2 for a probe is also irradiated to the first layer 5A and its reflected laser beam L3 is measured by a light interferometer 8. Based on the light interferometer, a direct vibration generating on the surface at a moment when the pulse laser beam L1 is irradiated to the first layer is detected, and a reflected vibration exposed on the surface of the first layer after the direct vibration is reflected by a second layer can be also detected. A time difference detecting the two vibrations becomes smaller in proportion to a remaining thickness δof the first layer.  Therefore, the time difference is measured at first when the above-described thickness becomes a predetermined thickness, and then, a via-hole processing is stopped when the time difference becomes within a predetermined value. Alternately, the time difference when a degree of a vibration exposed on the surface of the first layer becomes equal to and more than a predetermined value, a via-hole processing may be stopped.
