摘要： Tilt of an optical storage medium is stably detected even when then the guide groove pitch is reduced and recording capacity is increased. On a disk with continuous grooves of a pitch Gp, part of tracks Gn−1 and Gn+1 adjacent to opposite sides of an n-th track Gn is eliminated, forming an area where the groove pitch is equivalent to 2·Gp. A push-pull signal from the area of groove pitch Gp and a push-pull signal from the area of groove pitch 2·Gp are differentiated to obtain a tilt error signal. Tilt can therefore be detected even when groove pitch Gp is reduced and storage capacity is increased, and a highly reliable data recording and reproducing apparatus can be provided at low cost.

摘要： A data recording method is provided in which data are recorded on a rewritable optical disk in a form of record marks which are uniform in width, and in which erasability in overwriting is much improved, thus ensuring a high-density storage of the data. A continuous strip of storage area which is smaller in width than a recording track is produced by irradiation of a first laser beam of a constant recording power, and discontinuous regions of the storage area having a width greater than the recording track are crystallized by irradiation of a second multi-value laser beam according to the data. As a result, remaining regions of the storage area are record marks used to represent the data.

摘要： When recording data, a disk jitter is detected by a rotary encoder to obtain a rotation synchronizing clock which coincides in time axis variation therewith. The data are written once into a memory and then, read out at a timing in accordance with the rotation synchronizing clock to be recorded on a disk, thus forming a disk in which data signals between each of adjacent tracks closely coincide in clock phase with each other. When reproducing the data, a reproduced signal reproduced by one beam is subjected to A/D conversion, then, delayed by one rotation of the disk successively through a first memory and a second memory to obtain respective signals of adjacent tracks, whereby the crosstalk component is canceled from the data signal of a targeted track by a calculation circuit.

摘要： An amplitude control device for controlling an amplitude of a data signal having an reference amplitude includes an A/D converter which converts the data signal to an n-bit digital signal, an extraction circuit for extracting the reference amplitude from the n-bit digital signal, a compactor for comparing the extracted reference amplitude with a predetermined amplitude to produce a first signal when the extracted reference amplitude is greater than the predetermined amplitude, and a second signal when the extracted reference amplitude is smaller than the predetermined amplitude. A counter counts up and down on receipt of the first signal and second signal, respectively, and produces an m-bit digital signal representing the counting result. A ROM stores a table in which the n-bit digital signal and the m-bit digital signal are used as an address for designating a value equal to the n-bit digital signal multiplied by a coefficient determined by the m-bit digital signal.

摘要： Information is recorded and reproduced with high quality by all of the information layers of an optical information recording medium. A recording wavelength generator (112) selects control parameters of a recording pulse sequence for forming marks, on the basis of combinations of a mark length of a mark, a first space length of a first space immediately before the mark, and a second space length of a second space immediately after the mark. A laser drive circuit (111) records the marks by the recording pulse sequence determined by the selected control parameters. The first space length is classified into m types (m is an integer) and the second space length is classified into n types (n is an integer). An absolute value of a difference between two predetermined control parameters from among (m×n) control parameters selected during recording on a second information layer located on an incidence side of the laser beam with respect to a predetermined first information layer from among N information layers is equal to or greater than an absolute value of a difference between two predetermined control parameters from among the (m×n) control parameters selected during recording on the first information layer.
