Is inserted from the card insertion slot 12, the operation step S2
Then, the magnetic read is performed via the magnetic read / write unit 10 and the magnetic write is performed in the operation step S3. In parallel with the operation steps S1 to S3, when the rewritable card 11 is inserted, the outside air temperature (t) is detected by the outside air temperature detection sensor 1 respectively.
The data is read by the outside air temperature detection sensor detection circuit 2 and the resistance value (R) of the heating resistor 13 of the erasing head 3 is detected.
Is detected by the heating resistor resistance detection sensor 4, and data is read by the resistance detection sensor detection circuit 5.

Next, the outside air temperature (t) detected by the outside air temperature detection sensor detection circuit 2 and the resistance value (R) detected by the resistance value detection sensor detection circuit 5 are collated, and an appropriate value is read from the erasure matrix storage unit 6a.

FIG. 6 is a diagram showing in detail a third embodiment of the erasure matrix storage section 6 of the card recording device 20 of the present invention.

Referring to FIG. 6 and FIG. 1, the resistance value (R) of the heating resistor 13 is detected by the heating resistor resistance detection sensor 4 and the data is read by the resistance detection sensor detection circuit 5 to carry the card. The speed (V) and the set erase temperature (T) are selected from the erase matrix storage unit 6c.
