Bulk eraser for optical memory media |
摘要 |
The entire data content of a thermally erasable optical memory medium is erased simultaneously by irradiating the entire signal-retaining layer of the medium with light in such a manner that the signal-retaining layer is preferentially heated over other layers in the medium, particularly other thermo-optically active layers if any are present. The irradiation is most effectively achieved with a flash of light at high intensity and short duration.
