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 Elementis formed on one side (surface) of Head Substratelengthwise. The Temperature Measurement Resistive Elementis formed on the same side of the Head Substratesurface. The other side of the is facing the Heat Sinkto hold the Head Substrateand the Thermal Resistive Layeris 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.
