Image data is transmitted from an image input apparatus to an information processing apparatus. Specific information (e.g., photographing information) that specifies the image data, and identification information (e.g., a disk name) that identifies an optical disk on which the image data is recorded, are added to the image data. Further, the specific information and the identification information are stored in a storage device. Subsequently, specific information that matches with an input keyword is searched from the specific information stored in the storage device. Then, the searched specific information and the identification information corresponding to the searched specific information are displayed in a list on a display. By performing a keyword adding process and an image searching process, the optical disk containing desired image data can be easily specified. Therefore, desired image data recorded on the optical disk can be easily searched.

An optical disc cartridge for storing an optical disc. The cover of the optical disc cartridge absorbs or filters ambient light which may damage information stored on the disc after prolonged exposure to the ambient light. Preferably, the disc cartridge cover allows some visible light to pass in order to allow a user to read label information on the disc. The color of the cover may be transparent to visible light, allow only specific visible wavelengths of light to pass, or be opaque, as long as the amount of ambient light reaching the disc stored within the disc cartridge is reduced. The disc cover may be made of a single layer or include a base layer with one or more thin films thereon.

An information processor, wherein the information can be maintained without depending on the storage capacity of the memory portion and the searching for the information can be simplified. According to the information provided from outside and stored in the memory portion, the specific information for specifying this information is sorted and maintained. When the capacity not recorded yet in the memory portion is smaller than the basic information amount, a part of the information stored in the memory portion is stored on a portable information-recording medium and is erased from the memory portion. The identification information for identifying the information-recording medium recorded with the information is corresponded to and stored in the specific information corresponding to the information erased from the memory portion in the specific information that has been stored and maintained. As a result, in the case when the information is assigned, the place maintained (stored or recorded) with this information can be specified according to the specific information.
