A heating head which functions as an erase head for quick operation can be turned off while not in use yet it can turn on when it is used (on-demand operation) and operates stably without over-heating even for the long operation, re-writable media record erasing equipment and erasing method. At least one strip of Heating Resistive Element 2 is formed on one side (surface) of Head Substrate 1 lengthwise. The Temperature Measurement Resistive Element 3 is formed on the same side of the Head Substrate 1 surface. The other side of the is facing the Heat Sink 5 to hold the Head Substrate 1 and the Thermal Resistive Layer 4 is sandwiched. When the re-writable media record is erased, the media is moved across the erase head after the temperature of the temperature measurement resistive element reaches the predetermined level.
