Abstract:
A data search system for searching a data sync pattern stored in an optical disc by using a physical address is disclosed. The data search system comprises a physical address decoder, a data start indicator and a data sync pattern search circuit. The physical address decoder decodes a physical address signal read from the optical disc to obtain the physical address of a current position. The data start indicator generates a start search signal when the pickup head indicates a predetermined physical address to decide a start position. The data sync pattern search circuit searches the data sync pattern of the data from the start position to determine a cluster area of the data following the data sync pattern. The data search system further comprises a window generator, generating a window interval starting from the start position to search the data sync pattern therein.
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.

This invention is a write-once near-field optical medium using a zinc oxide nano-structured thin film as the localized near-field optical interaction layer. This write-once near-field optical medium is a multi-layered body at least comprising: (a) a substrate of transparent material; (b) a first protective and spacer layer formed on one surface of the substrate, which is made of transparent dielectric material; (c) a zinc oxide nano-structured thin film which is capable of causing localized near-field optical interactions; (d) a second protective and spacer layer formed on the localized near-field optical interaction layer, which is also made of transparent dielectric material; (e) a write-once recording layer; (f) a third protective and spacer layer formed on the write-once recording layer, which is also made of transparent dielectric material. Ultra-high density near-field optical recording can be achieved by the localized near-field optical interactions of the zinc-oxide (ZnO) nano-structured thin film that is in the near-field region of the write-once recording layer.

Abstract:
The invention provides an optical measurement device for measuring light to be inspected. The optical measurement device comprises a light receiving module, a light splitting module, and a plurality of color filters. The light receiving module is used for converting the light to be inspected into a first parallel light. The light splitting module is used for splitting the first parallel light into a plurality of parallel lights to be inspected. Each color filter receives at least one of the plurality of parallel lights to be inspected. The plurality of parallel lights to be inspected filtered by the plurality of color filters are used to calculate tristimulus values in the CIE color space.
