摘要： A phase change medium, a device and a method for driving a phase change medium are proposed that allow writing at high speed and erasing at low speed. The proposed low-speed erasing option must be seen as a formatting option that can be applied to the whole medium (or to part of the medium) so as to put the medium (or part of the medium) back to a virgin state. With the invention, direct overwriting of data is not possible: the data have first to be erased at low speed before new data can be written on the medium at high speed. According to the invention, the medium is rotated at a linear velocity that depends on the selected operating mode, the linear velocity applied in the writing mode being much higher than said maximum crystalline velocity, and the linear velocity applied in said erasing mode being equal to or lower than said maximum crystalline velocity. Application: DVD+R high-speed.

摘要： A tracking error (TE) signal is formed from a single spot on a photodetector 25 to improve the robustness in optical disc applications having a reduced track-pitch. Reduced track pitches are employed in high data capacity optical disc formats. By using high frequency cross-correlation of a central aperture signal, the differences within the left 21 and right 23 detector halves yield a divergence from the zero crossing that produces a more pronounced tracking signal. The more pronounced tracking signal is insensitive to incoherent cross talk in multi-layer discs.

摘要： The present invention provides a method and apparatus for robust tracking at narrow track-pitches on optical discs, enabling higher densities on Blu-ray Discs (5) as well as near-field discs. Increasing radial density results in loss of radial diffraction within the numerical aperture of the lens. Due to this loss in diffraction, current tracking methods, such as Push-Pull and Differential Phase Detection (DPD), will stop working. The invention provides a method and apparatus that relies on cross-correlating the central aperture (CA) signals of 3 optical spots (22, 24, 26) that are positioned such that there are a central spot (24) and spots (22, 26) positioned to the left (22) and right (26) of the central spot (4). By using CA signals, the tangential diffraction is used, which is hardly affected by a track-pitch reduction.

摘要： A record carrier has information represented by high density read-only marks in a track. The read-only marks (74,75) are optically readable according to a predefined high-density data format such as CD or DVD via a beam of radiation by first variations of the radiation. The record carrier has a recordable layer (70) for writing recorded marks (72,73) in a recording area of the record carrier, which recording area extends over the track (9) carrying the read-only marks. The recordable layer (70) is arranged to generate second variations of the radiation by a difference between an unrecorded state and a recorded state. A recording device writes recorded marks on top of the read-only marks. A read device recovers the first and second variations, and detects the read-only marks and the recorded marks from a same part of the track.
