Paper Abstract

The design of a write-once-read-multiple optical disc drive head using an 780 nm 20 mW diode laser is presented. To achieve high density data storage, the laser is collimated and aberration corrected before it is focused by a .50 NA objective lens onto the disc. The light diffracted back from the disc is used to generate an RF data signal as well as error signals for focusing and tracking. Detailed design requirements and considerations are discussed.
