Abstract

This paper describes the designing pregroove dimensions to achieve stable data read-out. The spot size detection method and the push-pull method are used for focusing and tracking error signal detection, respectively. Experimental and theoretical results show that pregroove crosstalk and decrease in light intensity due to groove diffraction become smaller as the edge gradient of the pregroove decreases. The permissible range of the depth for a triangular pregroove is 40% larger than that of a rectangular pregroove. The triangular pregroove depth to attain the maximum tracking signal efficiency is about 100 nm for a refractive index of 1.5.
