Abstract
A recording apparatus comprises a recording head arranged to record signals on a recording medium; a motor for shifting a relative position between the recording medium and the recording head; and a control circuit arranged to apply electric energy to the motor in starting the motor either in a first mode in which the electric energy is limited to a first value or in a second mode in which the electric energy is limited to a second value which is lower than the first value. Also disclosed is a motor control circuit which is highly suited to the recording apparatus. Detecting apparatus is also included to detect whether the power source is an A.C. adapter or a battery.
