摘要:
A storage apparatus includes a key control part to judge a validity of a data access from a request source based on authorization information received therefrom and authorization information created from an enciphering key included in enciphering key information received from a key management apparatus, and a control part to make the data access to the recording medium using the enciphering key in response to an access request from the request source, if the validity of the data access is confirmed. The authorization information from the request source includes a unique code created from the enciphering key if an authentication is successful in the key management apparatus in response to an authentication request from the request source.

摘要:
A key data recording device includes a key data recording medium section which stores key data of the encrypted data; and a reading/writing section which reads and writes the key data from and into the key data recording medium section, which sections are contained in a cartridge casing accommodatable in a library unit. When the cartridge casing is irregularly ejected from the library unit, the key data recorded in the key data recording medium section is deleted. This configuration can enhance the confidentiality of encrypted data because the key data is not leaked even when the recording medium in which key data of the encrypted data is recorded is carried away.

A storage apparatus includes at least one device insertion section, at least one robot, a replacement detection section, a first determination section, and a movement section. A device can be inserted into the device insertion section. The robot has a moving mechanism. The replacement detection section detects a start of the replacement of the device. When it is detected by the replacement detection section that the replacement of the device is started, the first determination section determines a position of the device insertion section at which the device is replaced. The movement section moves the robot so as to close an opening formed by removal of the device from the device insertion section based on the determination result of the first determination section.

There is provided a library device which can be restored to working order quickly and reliably even when a control board containing information necessary for the operation of the library device is replaced. The library device includes a cell array which consists of an array of multiple cells each of which contains one cartridge containing a magnetic tape, magnetic tape drives in which the cartridges are removably mounted and which access the storage medium contained in the cartridges, a robot which transfers the cartridges between the cell array and the magnetic tape drives, a main control board which controls the operation of the entire library device, a barcode label which represents ID information for identification of the library device, and cell flags which are marks used to recognize the locations of the cells composing the cell array.
摘要:
Radio tags storing parts identifying information are arranged for the individual constituent modules such as tape drives and conveying robots of the library apparatus. Upon every rise of the apparatus, the conveying robots are moved to positions permitting read of the radio tags arranged on the individual constituent modules. The parts identifying information such as the serial number is read by the tag reader and stored in the non-volatile memory. When this is different from the serial number read in the preceding run, stored in the non-volatile memory, it is determined that the part has been replaced. The statistical information of the number of operating runs is then cleared, and management of the parts service life is started.

The ratio is calculated between a first number of pixels and a second number of pixels on an image sensor. The first number of pixels is counted between two certain points projected on the image sensor from a first section of a plane. The second number of pixels is counted between two certain points projected on the image sensor from a second section, adjacent to the first section, of the plane. The number of pixels between two certain points increases if the image sensor gets closer to the plane, while the number of pixels between two certain points decreases if the image sensor gets remoter from the plane. The inclination of the image sensor can be determined relative to the plane based on the ratio between the two numbers of pixels. The attitude or inclination of the image sensor can in this manner be detected with a high accuracy.

The recording media recording an encrypted data or non-encrypted data therein, wherein the management of the recording media is reinforced by protecting the recording media (cartridge 8) from taking out without authorization etc. Recognition information is generated to identify that the recorded data in the recording media is an encrypted data or non-encrypted data, and record the recognition information in the recognition tag. The recording media has the recognition section 10 having the recognition information to identify whether the recorded data is an encrypted data or non-encrypted data.

Disclosed is a WDM network which has: a lightwave path which connects between clients and each of which is provided with an overhead, and a sub-network which is defined by dividing the WDM network. In this WDM network, the sub-network has a partial lightwave path to go through the sub-network, the overhead has a partial lightwave path supervisory control information region which is terminated at both nodes of the partial lightwave path, and when a fault occurs on a lightwave path, the fault information of partial lightwave path including the position information of fault occurred is added to the partial lightwave path supervisory control information region of the overhead.
