Title: Recording method

IPC: G11B7/244
Filed: 1985-04-16
Abstract: PURPOSE:To enable high density and high resolving power recording, by irradiating a medium comprising a diacetylene derivative compound with laser beam having a wavelength in a definite range according to input information. CONSTITUTION:A recording medium A, to which a diacetylene monomolecular built-up film 14 obtained by building up diacetylene monomolecular film layers 6, 20, 40, 60 was formed, is irradiated with argon laser beam (its output ; 7mW, its wavelength ; 488 nm) 15 in a dark plate according to a pattern to change the color of the irradiated part to blue to perform the recording of information. Regeneration is performed by scanning the recording medium A by He-Ne laser beam (output ; 1mW, a wavelength ; 633 nm) 18 and detecting the transmitted beam thereof by a beam receiving element. Because the laser beam non- irradiated part 17 is transparent, beam with a wavelength of 633 nm is not almost absorbed and transmitted through said transparent part and transmissivity comes to 70% or more while the irradiated part absorbs the beam of 633 nm and, as the built-up number of monomolecular films increase, absorption is performed more well. Because the contrast between the irradiated part and the non-irradiated part is high, a regeneration signal having a high S/N ratio is obtained.
