摘要: In optical disc systems, read-out is hampered because of spherical aberrations resulting from cover layer thickness variations or because discs consists of multiple layers. The aberration correcting apparatus (1) of the present invention is arranged to correct such an optical aberration. Therefore, the aberration correcting apparatus (1) comprises a fluid chamber containing a first fluid and a second fluid having different indices of refraction. The first (5) and second fluid (6) are in contact over a meniscus (7) acting as a refractive surface, wherein the shape of the meniscus (7) can be influenced by a magnetic field generated by a magnetizing coil (20).

摘要: An optical recording apparatus with a small form factor optical drive for driving an optical record carrier is operable in different accessing modes having different data rates depending on the power mode of the recording apparatus. A Switch is provided in the recording apparatus for switching a controller for accessing the optical record carrier for reading data from or recording data to the optical record carrier. A first accessing mode has a low data rate and is used in a low power mode, while a second accessing mode has a high data rate and is used or allowed to be used in a high power mode.
