It is an object of the present invention to provide a method for recording information in an optical recording medium with a good direct overwriting characteristic. The method for recording information in an optical recording medium according to the present invention forms record marks in a recording layer containing a phase change material by modulating the power of a laser beam between a plurality of power levels including a recording power Pw, an erasing power Pe and ground power Pb. The erasing power Pe is set to a level within a region where a reflection coefficient of a region between neighboring record marks approaches a reflection coefficient of the record mark as the erasing power Pe increases. As a result, a good overwriting characteristic can be obtained when data are recorded at a high linear velocity.

A resin for use in manufacturing wet friction materials which contributes to enhancing durability of manufactured wet friction materials, a manufacturing method thereof, and a wet friction material having excellent durability are provided. The resin for use in manufacturing wet friction materials can be obtained by reacting phenols with aldehydes in the presence of at least one basic catalyst, which contains a water-soluble phenolic resin as a main component. Further, the manufacturing method of the resin for wet friction materials includes a step of reacting phenols with aldehydes in the presence of at least one basic catalyst to obtain a water-soluble phenolic resin having a predetermined water percentage. Furthermore, the wet friction material is manufactured by impregnating a base material with the resin for wet friction materials.
