Abstract
An erasable optical disk drive system is disclosed which utilizes an electron trapping media coated on the disk surface to store data in the form of light energy. Data is written onto the disk, which is contained in a light-tight contamination-free environment similar to a Winchester hard disk drive system, using a near infrared light laser beam. Data is read from the disk using a visible light laser beam. The entire optical disk drive system is designed to fit within a standard mini or 51/4 inch disk drive form factor for personal computers.
