ABSTRACT:
There is provided a WORM type organic optical recording media comprising a recording layer, a reflective layer and a protective layer which are formed in sequence on a substrate, the recording layer consisting of near infrared absorbing dye able to absorb a laser beam and to generate heat and of a thermosetting or photocuring resin. The organic optical recording medium can be prevented from being rewritten by heating up to 50.degree. C. or irradiating with a UV light, said dye being capable of absorbing near infrared rays and generating heat.
The medium exhibits stable reading characteristics of at least 45 dB even after irradiating with a light with a short wavelength. In addition, it also has a function of record locking by curing the resin of the recording layer, so that, once recorded, rewrite or additional recording is not allowed therein. Consequently, it is of high data storage density, high data rates and long data archival capabilities, useful as a medium for recording a variety of information or pictures.
