摘要： A method and system are presented for use in at least reading data in a three-dimensional optical data carrier having at least one reference layer and at least one data layer. A recording/reading beam and a reference beam are focused onto the optical carrier through a common optical element creating two focal spots in different optical planes. Movement of at least said optical element is controlled such that the focal spot of said reading/recording beam tracks a data track in an addressed data layer, said controlling comprising identifying a change in an error signal from the reference layer during the reference beam tracking the reference layer, thereby adjusting a tracking target for control of the movement of the reference beam.

摘要： An optical system is presented for use in at least one of data reading and recording processes in an optical data carrier. The system comprises a light source system; one or more light directing arrangements; and a detection system. The light source system is configured and operable for generating at least one of recording and reading light beams to illuminate the carrier from a first side so as to record data within said carrier and/or read the recorded data. The one or more light directing arrangements is/are configured for directing said recording and/or reading light beams towards said optical data carrier. The detection system comprises a first detector unit configured and operable for tracking a trajectory of the recording or reading light beam while scanning the carrier, by detecting a light component coming from said first side of the optical data carrier while being recorded or read, and generating data indicative thereof; and a second detector unit having a high bandwidth collection and configured and operable for receiving a light response signal coming from the opposite second side of said carrier, and generating data indicative thereof.
