Abstract

[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.

First claim

The invention claimed is:

1. A cartridge memory for a recording medium cartridge, comprising:
a memory unit that 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; and
a capacity setting unit configured to be capable of setting, to the memory unit, 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.

2. The cartridge memory according to claim 1 , wherein
the capacity setting unit is configured to be capable of expanding the data storage area limited to the first capacity to a second capacity capable of storing management information relating to the second information recording medium.

3. The cartridge memory according to claim 1 , wherein
the memory unit has a memory capacity of not less than 32 kilobytes, and
the capacity setting unit sets a data storage area having the first capacity of not more than 16 kilobytes to the memory unit.

4. The cartridge memory according to claim 1 , further comprising
a voltage generation unit that includes an antenna coil for transmission/reception and receives a signal magnetic field from an external device to generate a voltage.

5. A recording medium cartridge, comprising:
a first information recording medium configured to be capable of recording information with a first data track number; and
a cartridge memory that includes a memory unit having 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 the first data track number, and a capacity setting unit configured to be capable of setting, to the memory unit, a data storage area limited to a capacity capable of storing management information relating to the first information recording medium.

6. The recording medium cartridge according to claim 5 , wherein
the first recording medium is a magnetic recording medium.

7. The recording medium cartridge according to claim 6 , wherein
the first recording medium is a tape-like recording medium.

8. The recording medium cartridge according to claim 7 , wherein
the first data track number is not less than 6000.

9. A method of producing a recording medium cartridge, comprising:
preparing an information recording medium configured to be capable of recording information with a first data track number and a cartridge memory having a memory capacity capable of storing management information relating to a second information recording medium capable of recording information with a second data track number larger than the first data track number; and
setting, to the memory unit, a data storage area limited to a capacity capable of storing management information relating to the first information recording medium configured to be capable of recording information with the first data track number.
