Abstract
Vehicle information such as vehicle speed, engine rotational speed when a vehicle runs are collected and converted into numerical data every constant period of time and these numerical data are written and recorded into a memory module. The memory module has therein a non-volatile memory and is detachably provided to a write unit attached to the vehicle. The data writing and power supply to the memory module from the write unit are executed by the contactless coupling using induction coils.
