ABSTRACT:
In a method for magnetically recording a vehicle condition, a voltage proportional to a vehicle speed is sampled at a predetermined interval and converted into a code signal which is temporarily memorized by a memory. When the memorized data reach a predetermined amount, the data are transferred to be recorded by a magnetic tape for a period which is short enough not to prevent the memory from memorizing. When all the data have been recorded, a completion signal is generated to stop the tape, whereby the inter record gap is limited to minimum length.
