    Abstract: This invention relates to a read-only near-field optical disk using a zinc-oxide (ZnO) nano-structured thin film as the localized near-field optical interaction layer. This read-only near-field optical disk is a multi-layered body at least comprising; (a) a transparent substrate with pre-recorded pits or marks; (b) a reflection thin film; (c) a zinc-oxide (ZnO) nano-structured thin film which is capable of causing localized near-field optical interactions; (d) a first and a second protective and spacer layers formed above or below the localized near-field optical interaction layer, which are also made of transparent dielectric material. Ultrahigh density near-field optical readout can be achieved by localized near-field optical interaction between the zinc-oxide (ZnO) nano-structured thin film and the reflection layer on pre-recorded structure.

In one embodiment, the servo calibration mark detection circuit comprises a summing processor, a slicing level generator, and a comparator. The summing processor sums an intensity of a light beam reflected from both an inner groove and an outer groove to obtain a first signal. The slicing level generator generates a slicing level. The comparator then compares the first signal with the slicing level to obtain a second signal, wherein the second signal indicates a first location of a first servo calibration mark recorded on the inner groove and a second location of a second servo calibration mark recorded on the outer groove.
