摘要： A disk unit(10) including an optical lens (14). A laser beam is shone onto the recording surface of a magneto-optic disk (68) via the optical lens (14), and a TE signal or RF signal is detected based on a laser beam reflected off the recording surface. Then, an MPU (50) displaces the optical lens (14) toward an optical axis direction, and a TE signal detection circuit (42) or RF signal detection circuit (60) detects a TE signal or RF signal at an individual displaced lens position. Laser power is regulated by the MPU (50) so that the amplitude of the detected TE signal or RF signal is below a saturation value. The position of the optical lens (14) is controlled so as to maximize the amplitude of the TE signal or RF signal detected after a parameter adjustment.

摘要： A record medium where data having a high error correctability is recorded at high effective recording density, its recorder, and its reproducing apparatus are disclosed. The recorder comprises an encoding unit that creates coded data by encoding input data by an encoding method such as a run-length encoding method, divides a data stream containing the coded data into data blocks, and outputs the data blocks, a data adding unit that adds data having the same value as the coded data of the last one bit of the previous data block of at least one data block to the first part of the at least one data block, and a recording unit. Thus, the recorder records the data blocks including the added data in prepit areas of the record medium and data recording areas thereof separated by the prepit areas.

摘要： Disclosed herein is an optical disc apparatus for applying a light beam to a surface of an optical disc and detecting a return light beam from the surface of the optical disc. The apparatus includes a light detector (51, 52) for detecting the return light beam having: a first divided area and a second divided area which are divided from each other at the center of the return light beam in a direction perpendicular to a track on the surface of the optical disc; and a third divided area and a fourth divided area which are positioned respectively outwardly of the first divided area and the second divided area in the direction perpendicular to the track. The first and second divided areas are positioned so as not to overlap an area where zeroth-order light and first-order light contained in the return light beam overlap each other.

摘要： A DVD video player with a build-in CD-R drive in which a reproduction output is selectively outputted from a flash memory, a recording medium which starts reading in a short time, until the data on an optical disk can be reproduced. This makes it possible to improve the user interface, for example, to arbitrarily reproduce audio information from the flash memory to add music or a sound effect to a screen saver, to reproduce the effect sound, to reproduce a click sound corresponding to an operation of a key or a remote controller, or to announce the state, instead of the optical disk from which data cannot be read while the screen saver is in operation or the device is on standby and the like.

摘要： The invention relates generally to store information on magnetic or optical storage media by using one or more novel approaches alone or in combination. These novel approaches are capable of using at least one code which may comprise more than two values (figure 4d, 43). A first series of approaches for the storage of information applies generally to optical recording and reproducing system (figures 7-10, optical media 66), while a second series of approaches applies generally to electric or magnetic recording and reproducing systems (figure 1-2, magnetic medium 1), Each series of approaches is capable of storing information data in one or more codes (figure 4d, 42a, 42b, 42c, 42d) and the use of at least one higher order code which is different from the traditional binary code of '0' and '1'.

摘要： The invention aims at providing a substrate-holder wherein the substrates can be easily separated without friction. This is achieved by providing a substrate-holder comprising at least two substrate retaining elements (8, 9), having substantially the same circumference, for maintaining disc-shaped substrates placed between said two elements, at least one of the retaining elements (9) including a cavity (12) wherein the substrates are urged to be housed. At least one of the substrate retaining elements is provided with at least a magnet for maintaining together said retaining elements. Additionally, at least a recess (24) provided in the first of the substrate retaining elements enables a second retaining element to be gripped from the rear, while at least an opening (14) in said second retaining element enables the insertion of an element for retaining a handling device. The invention also concerns a method, as well as a device for maintaining substrates, said device comprising at least first and second substrate retaining elements, having substantially the same circumference, for maintaining disc-shaped substrates placed between said two elements, at least one of said substrate retaining elements being provided with at least a magnet for maintaining together said retaining elements. A handling device is used for separating the substrate retaining elements, said device comprising at least a retaining element for locking the first retaining element, as well as at least a gripping element, mobile relative to the retaining element, for gripping and moving the second retaining element. The grip element can be moved between an open position, releasing the second retaining element, and a closed position, wherein the second retaining element is gripped from the rear, said grip element being mobile in a direction substantially perpendicular to a junction plane of the substrate retaining elements.

摘要： A record carrier has a servo track ( 4 ) indicating an information track ( 9 ) intended for recording information blocks. The servo track ( 4 ) has a periodic variation of a physical parameter at a predetermined frequency and modulated parts for encoding position information at regular intervals. The modulated parts start with a bit sync element and are of a data type having a data bit element, or of a word sync type having a word sync element. The word sync element and the data bit element are modulated according to a same predetermined type of modulation of the periodic variation. The effective strength of a modulated element is the number of periodic variations that are substantially different and available for detection of that element. The effective strength of the word sync element and of the data bit element are equal.
