摘要： A method and apparatus for retrieving information from a three dimensional storage medium uses a three dimensional storage medium having an active medium capable of exhibiting first and second states, a data unit being represented by the ratio between the concentration of the first and second states in a given volume portion of the medium and a data sequence is represented by a sequence of data units. The active medium is irradiated with light as to concentrate light flux through a volume portion of the storage medium so as to generate in the volume portion a detectable non-linear optical response characteristic of the concentration ratio, which is detected and used for tracking.

摘要： A method and system for correcting tracking errors in an optical storage medium having multiple tracks arranged in different layers of the optical storage medium, directs a reading spot that is nominally focused on to a track in the optical storage medium, and continually moves the reading spot in axial and radial directions so as to receive a signal having an amplitude which varies according to respective offsets from the track in radial and axial directions. The received signal is used to determine a direction of a respective offset from the track in radial and axial directions, and a location of the reading spot is adjusted accordingly.

摘要： A method for data inscription in an acrylic polymer-based photochromic medium is provided in which the photochromic groups are bound to the polymeric matrix. The data is inscribed by irradiating small volume portion with an electromagnetic irradiation that causes a change in state of the photochromic groups from a first to a second state. Said volume portion is heated so as to cause an increase in temperature of said portion at the time of data inscription. The heating may be external or internal. Internal heating makes use of additives that dissipate heat, following their irradiation, to their immediate vicinity. Provided is also a novel acrylic polymer-based photochromic medium comprising said additives.

摘要： A non-linear optical data carrier is presented. The non-linear optical data carrier is configured for recording therein information defined by a pattern of spaced-apart marks arranged in virtual data layers. The data carrier medium comprises a sub-stance capable of being excited by a first multi-photon interaction to be switched from its first state into a second state, where the first and second states of the substance provide different response signals to a second multi-photon interaction. The substance when in the first and second states have substantially overlapping linear absorption wavelength peaks, and first and second wavelengths involved in the first and second multi-photon processes as well as the response signals wavelengths are outside the linear absorption spectrum peaks of the substance in its first and second states. The basic size of the marks and spaces is larger in the first than in the second layer. Data layers are recorded by monotically changing the focal plane depth of the recording beam.
