  • the intensity of the reflected light differs depending on whether the light is irradiated on the groove or the land, and the position controller receives the signal and controls the position of the photodetector. Control is performed so that the position where the information is written is accurately irradiated with light.

  • the pre-group is meandered, based on a signal obtained by combining a reference signal having a predetermined frequency and the pre-format information.
  • the recording device demodulates the amount of reflected light from the pre-group, and performs recording and reproduction based on the obtained pre-format information.
  • Ma The pre-group is formed continuously in a PCA area, a PMA area, a lead-in area, a program area, and a read-out area provided in each area of the CD-R and the CD-RW.

Therefore, the program area is limited to a maximum of 00: 00: 00: 00 frame to 79:59:79, 74 frames, that is, 79: 59: 59: 75 frames, and more Therefore, the program area cannot be increased in capacity and lengthened.

  • the current recordable capacity is limited to about 1.33 GB for 150 minutes. It is preferably 120 minutes or less and 1.05 GB or less, more preferably 99 minutes or less, and 866 MB is preferable in terms of reliability of overnight writing and reproduction. Considering these, at present, even if N is set to 3 or more, it is not advantageous, and it is preferable to set N to 2.

After polishing the back surface of the third molding die 6a, the inner and outer diameters are punched out and dropped, thereby completing a donut-shaped third molding die 6a. Used as a stamper for manufacturing discs.

Abstract

Selon l'invention, si le début est à 78 min et 59 sec, trame 73, l'ATIP ne varie pas même si l'enregistrement temps progresse d'une trame, mais lorsque l'enregistrement temps progresse de deux trames, il représente 78 min 59 sec, trame 74. Lorsque l'enregistrement temps progresse de deux trames en plus, l'information de trame est remise à zéro en raison de report. En même temps, une seconde information provoque un report, et l'enregistrement temps représente 79 min 00 sec, trame 00. Ceci signifie que chaque fois que l'enregistrement temps augmente de deux trames réelles, l'information de trame augmente d'une trame. Ainsi, le support peut être conçu afin d'écrire/lire une double quantité d'information. Il est donc possible qu'un support d'enregistrement d'information optique montre ses performances absolues, même si on utilise un appareil de lecture ou d'enregistrement classique, et possède une capacité d'enregistrement accrue sans violation du standard imposé sur le support d'enregistrement d'information optique.
