[Object] A cartridge memory according to an embodiment of the present technology is a cartridge memory for a recording medium cartridge, including: a memory unit; and a capacity setting unit. The memory unit has a memory capacity capable of storing management information relating to a second information recording medium configured to be capable of recording information with a second data track number larger than a first data track number. The capacity setting unit is configured to be capable of setting a data storage area limited to a first capacity capable of storing management information relating to a first information recording medium configured to be capable of recording information with the first data track number.

Cartridge memory

A cartridge memory used for a tape cartridge, the cartridge memory including a communication unit that performs wireless communication, a control unit that transmits data to a recording/reproduction device according to a first communication standard via the communication unit, receives data from the recording/reproduction device according to the first communication standard via the communication unit, and transmits data to an information terminal according to a second communication standard via the communication unit, and a storage unit that stores data related to the tape cartridge.

Cartridge memory used for tape cartridge, tape cartridge, data management system, and cartridge memory used for recording medium cartridge

A cartridge memory is a cartridge memory used in a magnetic tape cartridge, including: an antenna unit; a storage unit that stores data; and a control unit that reads the data from the storage unit in response to a request from a recording/reproduction apparatus, adds an error correction code to the data, and transmits the obtained data via the antenna unit.

Cartridge memory for magnetic tape cartridge, control method therefor, cartridge, and recording/reproduction system

A cartridge memory used for a tape cartridge includes: a communication unit that communicates with a recording and reproducing device using a wireless communication method defined by an ISO 14443-2 standard which is a wireless communication standard; a non-volatile memory with a storage capacity exceeding 16 KB; and a control unit that writes or reads data to or from the non-volatile memory on a word-by-word basis (2 bytes at a time) or on a block-by-block basis (32 bytes at a time). The non-volatile memory includes a plurality of memory banks each having a storage capacity of 128 KB or less. The control unit writes or reads data defined by a magnetic tape standard to or from one or two or more first memory banks among the plurality of the memory banks, and writes or reads additional data to or from one or two or more second memory banks other than the first memory bank.

Cartridge memory, recording medium cartridge, and method of producing the same

A storage device writes data at a high speed. The storage device is provided with a data area and a control unit. In the data area, a write position is specified by a write address. Also, the control unit writes the data in the write address when instructed to write the data in the write address, and generates an address different from the write address in which the writing is performed as an alternative write address and writes the data in the alternative write address when the writing of the data is unsuccessful.

Storage device, storage system, and method of controlling storage device

There is provided a storage apparatus that includes an address obtaining section, and a write processing section. The address obtaining section is configured to obtain a normal write address and an alternative write address before data writing to the normal write address, the normal write address being designated as a destination of the data writing, the alternative write address being used when the data writing is failed. The write processing section is configured to perform the data writing to the normal write address when instructed for the data writing, and perform the data writing to the alternative write address when the data writing to the normal write address is failed.

Storage apparatus, memory controller, control method for storage apparatus, and program

A storage control apparatus includes: a pre-processing-execution determining block for determining whether or not either one of an erase operation and a program operation is to be executed as pre-processing in a write operation to be carried out on a predetermined data area to serve as a write-operation object; and a pre-read processing block for reading out pre-read data from the data area prior to the write operation if a result of the determination indicates that the pre-processing is to be executed. The apparatus further includes a bit operating block for carrying out: the pre-processing and one of the erase and program operations which is not the pre-processing as post-processing if a result of the determination indicates that the pre-processing is to be executed; and the post-processing without carrying out the pre-processing if a determination result indicates that the pre-processing is not to be executed.

Storage control apparatus to control pre-processing operations

Disclosed is an interface control circuit including an error detection unit, an error correction unit, and an adjustment control unit. The error detection unit is configured to detect whether an error occurs in error correction coded data transmitted via an interface. The error correction unit is configured to execute error correction processing of correcting the error when the error occurs. The adjustment control unit is configured to start adjustment processing of adjusting a transmission characteristic of the interface when the error occurs.
