Abstract
A cartridge memory is a cartridge memory used in a recording medium cartridge and includes an antenna section that induces an induced voltage by means of electromagnetic induction, a load modulation section including a load whose magnitude is variable, and a control section that measures the induced voltage and controls the load modulation section on the basis of the measured induced voltage.
