PCT No. PCT/JP97/01239 Sec. 371 Date Oct. 15, 1998 Sec. 102(e) Date Oct. 15, 1998 PCT Filed Apr. 10, 1997 PCT Pub. No. WO97/39868 PCT Pub. Date Oct. 30, 1997A process for recovering the resin contained in optical information recording media having either a thin metal film layer or a printed coating film layer, coated on at least one side of a resin substrate, which comprises the following steps of: (1) rolling the recording media, (2) bringing the rolled recording media into contact with hot water, (3) separating the coating film peeled from the recording media, (4) grinding the resulting recording media, (5) bringing the obtained small pieces of the recording media into contact with hot water to detach the thin metal film component, and (6) separating the detached thin metal film component from the small pieces of the recording media to recover and obtain the small pieces of the recording media. With this process, the coating layer can be removed effectively from the optical information recording media and the resin component in the recording media can be selectively recovered advantageously in industry.
