Storage medium, reproducing method, and recording method |
摘要 |
According to one embodiment, a write-once type information storage medium comprises an organic dye based recording material having sensitivity at a wavelength of 405 nm and at a recording wavelength in the range of 600 nm to 700 nm, wherein, when absorbance of a maximum absorption wavelength in the vicinity of 405 nm is defined as 1, the absorbance is 5% or more at any wavelength in the range of 600 nm to 700 nm. By adding another material having sensitivity at a comparatively long wavelength to a next generation dye recording material compatible with a short wavelength, a bar code pattern may be recorded even by a current BCA recording apparatus. |
