A medium processing apparatus includes a magazine including a plurality of storage units each of which stores the storage medium, the adjacent storage units being connected by a hinge member so that each of the storage units rotates on a shaft, a curved conveyance path that guides the magazine, a conveying unit that conveys the magazine along the conveyance path, and a medium moving unit that moves the storage medium between the storage unit of the conveyed magazine and the processing unit, and thus space saving is achieved.

Medium processing apparatus, storage apparatus and conveyance apparatus

A medium processing device includes: an information processor that performs at least one of record processing and read processing of information to each of recording media; a magazine that includes storage units which store the recording media, respectively, the storage units which adjoin each other being rotatably connected via a hinge member; a conveyance route that guides the magazine; a first introduction ejector that introduces or ejects the magazine; a second introduction ejector that introduces or ejects the magazine; a driving device that conveys the magazine introduced from any one of the first introduction ejector and the second introduction ejector, to a position where the magazine is capable of being ejected from another one of the first introduction ejector and the second introduction ejector; and a medium mover that moves each of the recording media between each of the storage units of the conveyed magazine and the information processor.

Information processing unit with curvilinear track

A cell stores a plurality of magnetic tapes. A conveyance mechanism manages movement of the magnetic tapes stored in the cell. An interlock switch cam moves in a predetermined direction when a pressing force from an inner door claw is removed. An interlock switch shuts off power supply to the conveyance mechanism when the interlock switch cam moves in the predetermined direction. A disabling button moves on a moving path of the interlock switch cam by receiving an instruction from an operator and prevents the interlock switch cam from moving in the predetermined direction.

Library device and control method thereof

In order to facilitate the management of the hardware key of a library apparatus employing the LTO system, a write function of a noncontact memory (CM: cartridge memory) contained in an LTO tape cartridge is implemented in a medium carrying mechanism part of the library apparatus, and during an insertion to a tape drive, the IDs unique to a library control part and to the medium carrying mechanism part are recorded in the non-contact memory and utilized as the hardware key of an encrypting apparatus. The hardware key written once is overwritten (erased) during an ejection, thereby preventing leakage of key information.

Apparatus and method for managing key in library apparatus

Disclosed is a method, for erasing data from a magnetic tape storage medium () housed in a cartridge () containing a memory in which are stored the last written track position (yy) of the last written, most recent information and the last track position (xx) of past information written in the past and remaining unerased, comprising: the step of reading out of the memory () the last written track position of the most recent information and the last track position of the past information; the step (S) of determining whether the data should be erased up to the last written track position of the most recent information or up to the last track position of the past information; and the step (S, S) of erasing the data up to the determined position, thereby shortening the data erase time of the magnetic tape while completely solving a security problem by making provisions to completely erase the data of the most recently written information or the data of the past information written in the past and remaining unerased.

Method for erasing data from magnetic tape storage media

A drive control apparatus receives an instruction from an upper unit, to mount a predetermined medium onto a predetermined drive unit. If a combination of the predetermined medium and the predetermined drive unit is determined as inappropriate, the drive control unit replies to the upper unit that the predetermined drive unit cannot be used. A combination of a medium and a drive is appropriate if both, the medium and the drive are suitable for any one of encrypted and unencrypted data.
