Abstract

See full text

A data write apparatus includes a card conveyor path, a recording head, a sensor circuit, a Central Processing Unit (CPU), a drive circuit, and an enable section. A magnetic card is conveyed in the card conveyor path. The recording head is arranged on the card conveyor path and performs a recording operation on the magnetic card by energizing a winding coil. The sensor circuit is arranged on the card conveyor path near the recording head and detects the magnetic card conveyed in the card convey or path to output a detection signal. The CPU outputs write data to be written on the magnetic card in response to the detection signal from the sensor circuit. The drive circuit energizes the winding coil of the recording head on the basis of the write data from the CPU to perform the recording operation. The enable section enables the drive circuit for a predetermined time after the write data is output from the CPU to limit energization of the winding coil of the magnetic head to a time equal to or less than the predetermined time.
