ABSTRACT:
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 Element2is formed on one side (surface) of Head Substrate1lengthwise. The Temperature Measurement Resistive Element3is formed on the same side of the Head Substrate1surface. The other side of the is facing the Heat Sink5to hold the Head Substrate1and the Thermal Resistive Layer4is 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.
