    摘要: The present invention relates to a holographic recording medium (9) adapted to store additional information for the recorded holograms, and to a holographic pickup (1) for a holographic storage system for use with the holographic recording medium (9).
    According to the invention, the holographic recording medium (9) has a holographic layer (94) for storing holograms and a servo layer (92) for positioning a light beam for reading and/or recording of a hologram relative to the holographic recording medium, wherein additional data can be recorded in the servo layer (92). A holographic pickup (1) for use with such a holographic recording medium (9) includes a detector (20) for retrieving the additional data recorded in the servo layer (92).

    摘要: An optical information recording medium (1) includes on a substrate (50), a ROM layer (20), a RE layer (40), an intermediate layer (30) separating the ROM layer (20) and the RE layer (40), and a light transmitting layer (10) provided farthest from the substrate (50). The RE layer (40) is an information recording layer provided most farthest from the light transmitting layer (10), and is a recording layer of BCA recorded in a format easily determinable as compared to an information recording format used in the ROM layer (20), and antifouling property of a surface of the light transmitting layer (10) is set based on the RE layer (40). This makes it easy for the recording and reproducing apparatus to confirm a disc type, allows for sharing one recording and reproducing apparatus with other types of optical discs, and simplifies the disc production. Furthermore, an optical information recording medium is accomplished, in which outdated data on the ROM layer is replaced by recording, on the RE layer, updated data obtained while Internet connection can be established.
