Paper Abstract

A lensless optical floppy disk drive which does’t have any optical lens between the optical head and the phase change (PC) type optical floppy disk medium have been developed. The head is a contact type, which had already been adopted in higher density magnetic floppy disk drives such as the LS120. The main point of this optical head is an antireflection (AR) coating technology of very low reflectivity on an output facet of a low cost laser diode which is as same as the laser diode installed in a commercial CD player. The AR coat of the laser diode and also the optical floppy disk medium are deposited on to both laser diode facet and to thin polyimid floppy disk substrate using an electron cyclotron resonance sputtering (ECR) method.
