Using the Panafile 1000, we have developed an optical disk memory equipment which is capable of storing 15,000 sheets of the letter-size document data into an optical disk of 20 cm in diameter. Then, we also developed a system which is designed to handle 700 optical disks, corresponding to data of 0.525 Terabyte. We further developed a Terabyte Multi-Disk Deck which is capable of monolithically handling 500 disks (0.38 Terabyte) of the optical disk. This system and multi-disk deck are effective in storing and retrieving the hand-written or stamped documents corresponding to significant volume of data.
