A drive preserves a default input password. When there is no password input from the user, the default input password is regarded as a user input password and is compared and collated with a password for access protection, thereby controlling the access protection. In this instance, if the default input password and the password for access protection have the same value, a collation coincidence is obtained. The drive permits the access without needing a password input of the user.

In order to achieve a magazine structure in which any necessary cartridge can be removed or inserted while a magazine is mounted in an autoloading device, a carrier unit is equipped with a lock releasing mechanism at the distal ends of openable/closable arms thereof so that a cartridge received in the magazine may be individually released from locking. This prevents any failure on the reading and writing of data due to removal of any wrong cartridge since the cartridge to be released can be defined by a programmable operation of the carrier unit.

A vendor ID is written to a system area of a write-once optical disk. When the write-once optical disk is loaded onto a write-once disk drive, a control CPU reads the vendor ID. The vendor ID is written into the header of software received through an interface unit. When the software is input to an SD circuit, the control CPU reads the vendor ID. The control CPU compares the vendor ID in the system area of the write-once optical disk with the vendor ID of the header of the software and checks whether or not the two IDs are identical. If the two IDs correspond to each other, the control CPU writes the software to the write-once optical disk.

A library apparatus is provided with a cartridge forced exit station for forcibly discharging a defective cartridge for safe removal by an operator. The cartridge forced exit station includes a storage rack for accepting the defective from an operating space side of a transferring mechanism in the interior of the library apparatus. The storage rack houses the defective cartridge. The storage rack is configured to selectively prevent access between a cartridge storage space in the storage rack and the operating space side.

A cartridge access station in a library apparatus for providing safe loading/unloading of a cartridge while maintaining a simple and compact arrangement of the library apparatus. The cartridge access station includes an communication space for establishing direct communication and connection between an operating space for a transferring mechanism in the interior of a library apparatus and an external space of the library apparatus. A rack is provided in the communication space to guide the entry/exit of a cartridge from both sides of the operating space and the external space and to hold the cartridge within the communication space.

In a method for preventing unauthorized use of a recording medium having a user accessible area and a user inaccessible area, first information is read from the user inaccessible area of the recording medium. The first information is compared with second information concerning a true recording medium (lawfully produced copy). It is then concluded that the recording medium is the true recording medium when the first information corresponds to the second information.

The present invention provides a library apparatus which is capable of ensuring the specification accuracy of a reference flag and a diagnostic cell to make sure the error correction at the initial stage (initial operation) while facilitating the accuracy adjustment of the reference flag and the diagnostic cell, thus allowing the certain insertion/extraction of a cartridge into/from a storage unit or a deck by an accessor. In the library apparatus according to this invention, the reference flag to be read out by a sensor on the accessor side to detect the absolute position of the accessor is disposed close to and integrated with the diagnostic cell into and from which a diagnostic cartridge is inserted and extracted by the accessor to verify the operation of the accessor. This invention is applicable to a large-capacity external storage system storing a large number of cartridges such as magnetic tape cartridges and optical disk cartridges.
摘要:
An information recording medium wherein the key information is recorded by arrangement of a unit area recorded irreversibly and a unit area not recorded irreversibly to effect the truth judgment of the medium in accordance with the result of whether or not the reproduction of the key information can be effected, the information recording medium where the illegal usage of the medium is adapted to be prevented without inputting the information on to the medium truth judgment into the processing apparatus by provision of the medium firm information, a reproducing method for the same, a truth judging method for the same, and a recording/reproducing apparatus for the same.
摘要:
An optical disk is divided into a plurality of sections at least one of which (a first section) is made a section (formatted in MS-DOS, for example) having a format different from the logical format of a CD-ROM. Publication data is optically recorded in at least one section (a second section) of the sections other than the first section in accordance with the CD-ROM logical format. A CD-ROM utilization tool that utilizes publication data in the CD-ROM logical format and a CD-ROM emulator for converting a request for access to the CD-ROM logical section issued by the CD-ROM utilization tool to a request for access to the optical disk are recorded in the first section.
摘要:
A method of preventing a fraudulent use of an optical disk having a read-write region and a read-only region, comprising the steps of: writing data for designating the boundary between the read-write region and the read-only region into a predetermined block of the optical disk; reading the data out of the predetermined block prior to the execution of the software recorded on an optical disk as an object of fraudulent use check; reading data out of a block which is assumed to be in the read-only region by reference to the data read out of the predetermined block, and writing the data read out of the block in the assumed read-only region into the same block; reading data out of a block which is assumed to be in the read-write region by reference to the data read out of the predetermined block, and writing the data read out of the block in the assumed read-write region into the same block; and judging that the optical disk as an object of fraudulent use check is not a fraudulent copy when the data writing operation is impossible in the block in the assumed read-only region but possible in the block in the assumed read-write region.
