摘要:
Des têtes d'enregistrement/lecture de signaux (32, 34) sont déplacées par rapport à une surface d'enregistrement (20) sur un support d'enregistrement stationnaire (18) ayant une surface séparée (16) sur laquelle des données visuelles sont enregistrées et affichées. Un mécanisme d'entraînement à différentiel (42) et des moyens de résistance réglables (72) assurent le déplacement des têtes le long d'un chemin prédéterminé sur la surface d'enregistrement à une vitesse constante.

The present invention includes a shooting portion (14) configured to shoot a surface of a disk (15) and output video data, a storage portion (17) configured to store the video data output from the shooting portion (14), a display portion (18) configured to perform video display based on the video data stored in the storage portion (17), and an output portion (19) configured to digitally output the video data stored in the storage portion (17) to the outside.
摘要:
An optical disc comprising: a first optical recording area storing first data represented by a secret code; and a second optical recording area including a barcode-like pattern (387a) representing second data containing information of an ID number for the optical disc, wherein the information of the ID number forms a secret code unlocking key for decoding the first data represented by the secret code into corresponding non-secret data.
摘要:
An apparatus for reproducing information from an optical disc having a transparent substrate and an optical recording layer, the optical recording layer extending on the transparent substrate, the optical recording layer having a first recording area storing data containing data represented by a secret code, the optical recording layer having a second recording area provided with a barcode-like pattern representing data containing information of an ID number for the optical disc, the apparatus comprising: first means for optically scanning the optical recording layer of the optical disc and reading out information from the optical recording layer; second means for recovering the data represented by the secret code from the information read out by the first means; third means for recovering the information of the ID number for the optical from the information read out by the first means; fourth means for using the information of the ID number for the optical disc which is recovered by the third means as a secret code unlocking key, and the decoding the data represented by the secret code which is recovered by the second means into corresponding non-secret data in response to the secret code unlocking key; and fifth means for outputting the non-secret data generated by the fourth means.
摘要:
In accordance with the invention, a fixture (10) is provided to receive a label (L) to be applied to a CD disc (13,15). The fixture includes a base (12) having a well (14) of a dimension approximately the shape of the label and CD disc. The label, after printing indicia thereon, is placed adhesive side up in the well of the fixture. Since the well also approximates the shape of the CD disc, the disc may be placed in the well first, within the bounds of the well of the fixture, with its unwritten side facing up. The disc or label is then overlaid on the other manually in the well, and pressed in place, to adhere the label to the disc. A pair of oppositely disposed cutouts are provided in the fixture to enable the composite card and adhered label to be removed from the fixture by inserting the fingers beneath the laminate and lifting it up from the fixture. The sidewalls (16, 18) of the well are rotatable and opposed edges are straight and arcuate so as to present when oriented to the interior of the well, circular or truncated shape to the interior of the well to accommodate different shaped discs.
