The patent describes a recorder having a rotary driven stylus mechanism electronically cooperating with an electro-sensitive recording paper modified to allow continuous unattended operation. An integral elongate stylus has a portion wrapped about an axis of rotation and the tip of a radially extending portion is brought to bear against the recording paper at a constant pressure and orientation irrespective of the accumulated erosion caused by prolonged operation. The aerodynamic resistance of a vane creates a force to displace the stylus to ensure its predetermined constant pressure and orientation as the stylus wears away to provide uniform operational characteristics over relatively long periods.
