摘要： A method for forming a thin film includes the steps of: supplying a deposition material in the form of a liquid onto a heated surface; heating and vaporizing the deposition material on the heated surface while the deposition material is undergoing movement; and depositing the deposition material onto a deposition surface. The deposition material is supplied onto a position of the heated surface where the vaporized deposition material does not reach the deposition surface.

摘要： A DVD-R 1 has a main information area 2 where data information is recorded in a track having a wobble, and first and second control data areas 3,15 each of which is disposed in an inner space closer to the disk center than the main information area 2. The information structure and physical structure of the first control area 3 are different from those of the second control area 15. In the second control area 15, predetermined physical format information and disk production information, for example, the last address of when data is written in the DVD-R 1, the maximum transfer rate or the like, are recorded. Thus, when the DVD-R 1 is reproduced by a DVD player etc., the physical format information and disk production information etc. recorded in the second control data area 15 are read. Thereby, the disk can be precisely identified without spoiling the physical format information, the disk production information or the like, and further illegal use of the DVD or another optical disk leading up to breach of the copyright can be effectively prevented.
