Small form factor optical disc drive for use in mobile electronic device |
摘要 |
A small form factor disc drive is structured to hold and play an optical data storage disc measuring approximately 32 mm in diameter and containing 1 GB of data per layer. The disc drive contains a blue wavelength laser, an objective lens having a numerical aperture in the range of 0.70-0.78 and conventional DVD-compatible controller electronics. This unique combination of elements allows a full-length movie or a video game to be displayed with DVD-quality on a cell phone or other portable hand held device.
