1. A recording apparatus having a recording head mounted thereon for recording, said recording head comprising means for generating thermal energy for recording and a temperature sensor for outputting an output value corresponding to detected temperature, said apparatus comprising:

  • mounting means for removably mounting a mounted recording head;

    head detecting means for detecting that said mounted recording head has been replaced on said mounting means with a replacement recording head;

    presuming means for presuming characteristics of said temperature sensor of said replacement recording head mounted on said mounting means based on a time-based change of the output value from said temperature sensor when replacement of said mounted recording head is sensed by said head detecting means; and

    correcting means for correcting a value based on the output value from said temperature sensor by processing data including the characteristics presumed by said presuming means.
