Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To narrow a pit so as to increase a recording density by performing exposure in a manner of overlapping two exposing beams in an advancing direction and exposing an overlapping part of spots irradiated with these two exposing beams so as to form an exposing pattern. SOLUTION: A light emitted from a laser light source is modulated, then divided into two light by a beam splitter, position-adjusted by beam steering or the like and then two exposing beams partially overlapped with each other are formed in an advancing direction. That is, the width Dp of a pit is formed equal to the width of an overlapped part S between the exposed spots SP1 and SP2 of the two beams. Then, a photoresist is set so as to expose only this overlapped part and thereby the pit width Dp is formed. At this time, by increasing a space between two optical axes and reducing the ratio of the overlapped part of the exposed spots SP1 and SP2 , the pit width Dp is reduced.

Further, various waxes can also be used for viscosity adjustment. A solvent used for the formation of the second softening layer 1c does not have to dissolve and swell the component of the first softening layer 16, but the component of the second softening layer 1c, if insoluble, can be used by dispersing it in a solvent. Subsequently, it is possible to make print appear sharply without giving any adverse effect to the first softening layer 1b and improve transferability with the help of a viscosity donative agent.
