IPC: G11B7/09
Filed: 1998-04-02
Abstract: PURPOSE: An apparatus and a detection unit are provided to scan a record carrier generating a tracking error signal which is more reliable. CONSTITUTION: A light beam modulated by information marks in a track on the record carrier is projected onto a detection unit(15) comprising four detectors. A reliable tracking error signal based on time differences between detector signals is obtained by comparing digitized signals of the detectors with a delayed signal Td when high-density is recorded. The time differences between the detector signals is the length differences between pulses having a nominal length of Td in the compared signals A and B. The compared signals A and B are low-pass filtered and combined to generate the tracking error signal TE.

Abstract: PURPOSE: An apparatus for measuring optical signal-to-noise ratio in a WDM optical transmission system to measure optical signal-to-noise ratio from the amount of noise generated when input optical signal is detected by an optical detecter, to efficiently maintain and manage the system. CONSTITUTION: An apparatus for measuring optical signal-to-noise ratio in a WDM optical transmission system includes an optical distributor for distributing an optical signal externally inputted and an optical power measuring unit(109) for measuring the intensity of the optical signal from a part of the distributed optical signals. The apparatus also has a noise measuring unit for measuring the intensity of noise generated when the optical signal is detected from the other part of the distributed optical signals, and an optical signal-to-noise ratio calculator(108) for calculating the optical signal-to-noise ratio from the intensity of the optical signal and the intensity of the noise.
