Eastman Kodak Co’s Verbatim unit in Sunnyvale, California has been very quiet indeed on its erasable optical disk drive since it announced the project in 1985 and showed a prototype of the product in 1987 – but the company says that it is now ready to put the thing into production. It also claims an average access time of 30mS for the 3.5 disk. As with most early erasable optical drives, the Verbatim 35/60 uses magneto-optical technology, where a change of magnetism at the recorded spot on the medium causes a phase change in the reflected light, and erasing is achieved by melting the spot to the point where the magnetism can be reversed. No details of price or delivery dates for the disk drive were available.
