摘要:
A information recording medium on which stream information including images or sound and management information of the stream information are digitally recorded includes a first recording region in which first management information of the management information for use in common in management of each stream information divided every predetermined data amount can be recorded, and a second recording region in which a reference unit of information obtained by adding second management information of the management information for use in management of divided individual stream information to the divided stream information can be recorded.
摘要:
In an optical disc in/from which data is recorded or reproduced by irradiating a storage area on the optical disc with a laser, information containing recording velocity information (RVI) for recording/reproduction, which represents a linear velocity different from the standard linear velocity, and write strategy information (WSI) corresponding to the recording velocity information is stored in a land pre-pit or the like on the optical disc.

摘要:
A base lens of a polyurethane resin comprising a polyisocyanate compound and a polythiol, a sulfur-containing polyol or the like is coated with a primer layer having a thickness sufficient for shock absorption, an organosiloxane-type, hard coat layer having a refractive index of 1.47 or more, and optionally a thin metal layer in that order. As having this constitution, the plastic lens has a mechanical strength resistant to striking energy of not smaller than 4 times the striking energy value of the FDA Standard, 0.204 joules, when the center thickness of the lens is from 0.7 mm to less than 1.2 mm. Since the latitude in the acceptable range for the conditions for the processing of the lens (relative to the thickness of each constitutive layer) is large, the producibility of the lens is high. An inhomogeneous layer may be formed between the adjacent layers, which reduces the reflectivity of the lens for transmitting light and prevents the formation of interference fringes in the lens. An ultraviolet absorbent, if added to the hard coat layer, can cut off ultraviolet rays, while preventing the base lens and the coat layers from being aged, and is helpful in protecting eyeballs.
