A magnetic code reading device and magnetic code reading method in an ATM or the like which after detecting a readout magnetic waveform including jitter, performs necessary transaction processing without performing uniform error processing in a predetermined case. The device comprises a magnetic head having a magnetic sensor for writing and reading magnetic code onto/from a magnetic recording medium, a timing disk for generating a timing pulse in correspondence with a moving distance of the magnetic head, and a controller for controlling the magnetic head and the timing disk, wherein upon reading of magnetic code on the magnetic recording medium where predetermined information is written in correspondence with the timing pulse, if jitter appears at relatively fixed intervals, corresponding to a rotational period of the timing disk, in a series of readout magnetic waveforms detected by the magnetic sensor, the controller recognizes the magnetic code based on the series of readout magnetic waveforms including the jitter, while if jitter is not related to the rotational period of the timing disk, the controller performs reading error processing.
