Study of Optical Data Storage with Green Laser
绿光光存储实验研究

To improve optical storage density, short wavelength laser and high numerical aperture (NA) objective lens are often applied. In this paper, an optical storage device with 532 nm laser and an objective lens of NA=0.65 is setup. An experimental result of a recording track of about 500 nm is obtained on CD-RW disk with this experimental device.
