CELL PHONE OR OTHER PORTABLE HANDSET CONTAINING MICROMINIATURE OPTICAL DISC DRIVE

摘要

A microminiature optical disc drive is mounted in a cell phone or other handheld portable device to provide a large data source for playing games, movies and other digital content on the device. The optical disc drive is manufactured to an extremely small form factor by, among other things, employing a blue laser beam and a high numerical aperture lens in the optics assembly.
