摘要:
A transmitting method of digital data whereby information data can be reproduced at a high precision. In order to retain digital data in sectors comprising a plurality of sync frames and sequentially transmit, the sync frame is comprised of the sync signal and the run length limited code which satisfies the limitations of the minimum run length and the maximum run length, and the sync signal includes the sync pattern constituted by a bit pattern of a run length that is longer than the maximum run length by only 3T and addition bit patterns which are arranged before and after the bit pattern and each of which has a urn length that is longer than the minimum run length. The sync signal includes a specific code which indicates a position in the sector and which enables the DC control to be performed.

According to one embodiment, an optical disc is the following the distance between a light incidence plane and the first recording layer is a minimum of 550 μm. The distance between the first and the third recording layer is a maximum of 72 μm. The distance between the second and the third recording layer is a minimum of 15 μm. The distance between the first and the second recording layer is about 31 to 40 μm. The reflectivities of the first and the second recording layer with respect to the first laser beam range from 18 to 27%, and the ratio therebetween is about 1.1 or less. The reflectivity of the third recording layer is below about 6%. The areal recording density of the third recording layer is three times or more as high as that of the first recording layer and the second recording layer.

Reinforcement of a system renewability is realized skillfully utilizing properties peculiar to a system. As a result, there is produced such a new effect as to similarly reinforce required specification with respect to copyright protection of a content recorded in a medium for exclusive use in reproduction and a recordable medium. In a system which encrypts information such as a content to record/reproduce the information, design is made so that encryption/decryption processing information differs for a device (software (S/W) main body device) whose main body is software constituted of a recording/reproducing drive of a recording medium and a personal computer (PC), a device (hardware (H/W) main body device) whose main body is hardware integrally containing a drive and data coding/demodulation processing, and the medium for exclusive use in reproduction and the recording medium.

A holding mechanism 10 for holding an ink ribbon 20 includes a transparent shell 11 and a board 12. The transparent shell 11 of the ink ribbon 20 is provided with wind slack preventive portions 11a to 11d which prevent rotations of a feed bobbin 21 and reel bobbin 22, and wind meandering preventive portions 11e, 11f which bears down an axial end 23a of a film 23. The ink ribbon 20 can be stably held by the holding mechanism 10 during a transportation and a loading thereof. The transparent shell 11 is provided with support portions 11g, 11f which improve a stability when loading.
摘要:
An information recording medium comprising a substrate having a recording surface provided with emboss pits or guiding grooves, a reflective film formed on the recording surface of the substrate, and a first protective film formed on the reflective film. This information recording medium is featured in that both sides of the information recording medium are constituted by a first surface provided with the protective film and by a second surface formed opposite to the first surface, and that an irradiated light beam is irradiated through the first surface, a recorded information being reproduced based on changes in light intensity of the reflected light beam. The distance between the recording surface of the substrate and the light incident surface is smaller than a thickness of the substrate, and a surface roughness "R" of the light incident surface meets a relationship represented by the following formula (1):R.ltoreq..lambda./(8n) (1)wherein .lambda. is a wavelength of the light beam, and n is a refractive index of the first protective film to a light having the wavelength .lambda..

According to this invention, in reproducing data recorded on a recording medium, reproduction of the data is limited on the basis of the distribution order, regional limitations such as different principles, different values, and regulation of morals, and time limitations which are recorded on the recording medium. Accordingly, when data recorded on a recording medium is reproduced, reproduction of the data can be limited based on limitations recorded on the recording medium.
摘要:
A bonding device and bonding process for a surface skin member of a vehicle interior component which can reliably fold back and secure a peripheral part of a surface skin member onto the reverse surface of a core member without involving any positional deviation between the core member and the surface skin member even when the width of the peripheral part is small. A block of elastic material is used for a lower die for mounting a surface skin member in a bonding station, and slide bars are arranged around the lower die in a peripheral part folding back station disposed adjacent to the bonding station for provisionally shaping the peripheral part of the surface skin member. Further, vertically moveable bars are arranged around an upper die for mounting the core member thereon for pressing the peripheral part of the surface skin member which has been provisionally shaped against the reverse surface of the core member.
