ABSTRACT:
An optical information medium comprises an optically transparent substrate and a protective layer formed on the substrate for protecting a record portion so that information which is optically readable by means of a laser beam can be recorded. A hydrophilic film is formed at a side opposite to a side through which reproduction light of the optically transparent substrate is passed. The film has a hydrophilic surface on which an aqueous printing ink is fixable. Printing is possible on the hydrophilic surface by use of an ink jet printer. A method for printing on the hydrophilic surface is also described.
