A product mark including a public key certificate issued with respect to an information-recording-medium manufacturing entity or information-recording-medium manufacturing equipment, and an encrypted volume ID calculated by computation based on a product-mark-associated value such as a hash value generated on the basis of the product mark, and a volume ID as an identifier set with respect to a given set of discs to be manufactured, are generated. The product mark and the encrypted volume ID are set as information for generating a key used for decryption of encrypted content, and recorded onto a disc by a reflective-film-removal recording method. Due to this configuration, the product mark and the encrypted volume ID as key generating information cannot be read from a pirated disc produced by physically copying a pit pattern on the basis of a legitimate commercial disc, thereby making it possible to prevent unauthorized reproduction or use of content.

The visibility of irregularities on the body tissue, such as a superficial microstructure or hypertrophy, is improved. Excitation light EL is emitted to a phosphor to excite and emit white light W. High absorption wavelength cut light is generated by removing components in high absorption wavelength bands A1 and A2, in which the absorption coefficient of hemoglobin in the blood is high, from the white light using a high absorption wavelength rejection filter. The subject is illuminated with the high absorption wavelength cut light, and image light of the reflected light is captured by a color CCD.

A data recording device, in the case where a data recording operation is suspended, even when a synchronization pattern cannot be detected due to a scratch of an optical disk or the like, a position where the last data is recorded is precisely detected so as to resume the recording operation without causing a joint. For this purpose, in resuming the suspended recording operation in the data recording device of this invention, reproducing pattern data corresponding to a pit pattern having been recorded in the optical disk is first reproduced. A synchronization pattern detection circuit detects a synchronization pattern and outputs a pre-complementation synchronization signal. A synchronization signal complementation circuit detects presence of a synchronization signal (synchronization signal pulse) and outputs a detection / loss signal to a synchronization signal non-detection counter. Also, when the synchronization signal is lost, the synchronization signal complementation circuit complements the synchronization signal and outputs a post-complementation synchronization signal to an address detection / complementation circuit and the like. The synchronization signal non-detection counter outputs a non-complementation signal when synchronization signals are continuously lost, so as to stop the resumption of the recording operation.
