Small form factor optical data storage disc and disc drive for use in mobile electronic device |
摘要 |
An optical data storage disc measuring 32 mm in diameter contains 1 GB of data per layer. The data is designed to be readable by a disc drive that contains a blue wavelength laser, an objective lens having a numerical aperture of 0.72 and conventional DVD controller electronics. This 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.
