Inexpensive safe light beam recorder |
摘要 |
A light beam optical recorder has a light emitting diode as a light source. Selecting the type of the LED used and the type of a photoresist employed with the selected LED results in creating pits of nearly laser quality. The recorder is substantially cheaper and also offers other advantages over a laser-type recorder.
