摘要： The present invention aims to provide a reproduced signal evaluation method and a write adjustment method for offering a Blu-ray disc having a large storage capacity with excellent media compatibility. An evaluation index L-SEAT is calculated through signed addition using a Euclidean distance difference calculated from at least one of target signals in which a focused edge is shifted to the right and left, and the quality of the reproduced signal is evaluated based on the evaluation index. Write condition adjustment using the index enables write adjustment not depending on SNR and achieving high adjustment accuracy.

摘要： A novel evaluation index is introduced so as to allow both a total evaluation of data recording and an evaluation of individual detection patterns. A data recording evaluation method includes a step of reproducing the result of data recording performed on an optical disk and identifying a predetermined detection pattern in a reproduction signal, a step of detecting the signal state of the reproduction signal corresponding to the predetermined detection pattern, and a first calculation step of calculating a first recording state evaluation index value based on the detected signal state and a reference condition which is identified from the predetermined detection pattern and adjusted so as to reflect the signal state of the reproduction signal. When there is a plurality of predetermined detection patterns, the method further includes a second calculation step of calculating a second recording state evaluation index value using the first recording state evaluation index value for each of the predetermined detection patterns. Data recording can be evaluated properly using the first and second recording state evaluation index values.

摘要： The optical disk writing system disclosed is one in which a data written on an optical data writing medium is verified essentially simultaneously with the writing on the medium. The written data is verified by detecting a timing of the light irradiated on the medium and by measuring return light doses at a rise and a fall of the light irradiated on the medium and comparing the doses thereof with predetermined reference values. The medium used is one which uses a phase transition reversible between a crystal state and an amorphous state for writing/reading/erasing of data on a data writing film and includes, a first protective film (122), a phase transition type data writing film (123), a second protective film (124), a reflection film (125) formed in this order on a transparent substrate (121). The thickness of the first protective film is set such that, of three reflectivities of the data writing film respectively in crystal, amorphous and melted states, the reflectivity in the crystal state and the reflectivity in the melted state are made different from each other, and the reflectivity in the amorphous state and the reflectivity in the melted state are made different from each other. A high speed writing operation can be carried out and an overwrite operation can be completed in one time disk rotation.

摘要： Systems and methods for data storage on an optical medium having a plurality of tracks include splitting a light beam into a higher power main beam and at least one lower power side beam that form corresponding spots spaced along a selected one of the plurality of tracks and selectively positioning and aligning the beams/spots along the selected one of the plurality of tracks using the higher power main beam to write data while reading previously written data using the at least one lower power side beam. The systems and methods may include correlating the read signal with a time-shifted write signal to provide a direct read after write capability to verify data written to the optical medium. In one embodiment, an optical tape drive includes an optical pickup unit (OPU) that generates a lower power satellite beam to read data directly after writing by a higher power main beam.

摘要： The invention relates to a "jump gap" servo mode provided to position an optical tape medium relative to a pickup head so that tracking may be reestablished after gaps in the servo tracks which occur in the pre- and post-amble fields. These gaps arise periodically because of a seam in the drum used to emboss the servo track on the tape medium. Also disclosed herein are other aspects of optical tape technology, tape manufacturing, and tape usage including: configurations, formulations, markings, and structure of the optical tape; manufacturing methods, systems, and apparatus including curing processes, coating methods, embossing, drums, testing, tracking alignment stamper strip; pick up head adapted for the disclosed optical tape; and optical tape uses including optical storage media devices for multimedia applications.

摘要： This optical disc drive has an optical pickup head that emits a light beam to an optical storage medium, detects the light beam reflected from the optical storage medium, and outputs a signal based on the received reflected light; a jitter measuring unit for measuring jitter in signals output from the optical pickup head; and an evaluation unit for determining from the measured jitter if the optical storage medium is good or defective. The jitter measuring unit measures jitter in a train of 3T or longer marks or spaces from an optical storage medium to which digital information is recorded as a train of marks or spaces of length kT based on a period T and an integer k of two or more.
