Method of recovering records in storage device and system for realising said method

Method of recovering records in a storage device in case of malfunction or damage to part of the storage device or distortion of data in the storage device, wherein memory of the storage device is partitioned into information areas of the same size and control areas, selected from different parts of the storage device. Each group of data to be stored is recorded in form of a set of code words in a corresponding information area. Three control sums are found, each according a predetermined formula, during each data recording using a corresponding computing unit. Each of the found control sums is then recorded in form of a code word with the same number in the corresponding control area, wherein each of the three control sums is stored in a separate area of the storage device. In case of malfunction or damage to part of the storage device, the computing unit calculates current control sums using formulae for each set of code words with the same numbers in all information areas. Values of the stored control sums and values of the current control sums are used to recover lost data by solving a system of equations.

Method of measuring optical data media, optical data medium, recording device and reproducing device

Method comprises four steps. The first step involves measuring the modulation depth of each layer of the optical data medium using an optical measuring system. At the second step, thickness between layers of the optical data medium is measured. At the third step, the reflecting power of each layer of the optical data medium is determined. At the fourth step, the modulation depth of each layer is converted to modulation depth for a standard optical system different from the optical measuring system, based on a value which indicates thickness between layers and a value which indicates the reflecting power of each layer.

Method of recording and reproducing sound using laser

Surface of a carrier is divided into sections which divide data in digital and analogue formats. An optical disc is used to simultaneously store, record and reproduce analogue and digital information on a spiral track. A varying relief is formed on the track, which reflects changes in sound waves from the source of the analogue signal on the information storage layer. When the record is read by an optical receiver of the reflected laser beam and the signal is converted from optical to analogue, the signal is varied according to duration and power of the reflected optical signal on the spiral track of the carrier.
