Abstract
An optical disk system using a blue laser diode and a single objective lens that has a numerical aperture of 0.7, is proposed. A sufficiently low jitt er value was obtained with a read-only disk having 17-Gbyte capacity. The p aper also includes discussion un the influence of the laser noise and RF mo dulation method on the playback signals.
