Automatic prompting for cleaning of magnetic disk heads

A method for cleaning transducer heads in a magnetic disk drive located within a device such as an electronic cash register comprising the steps of storing in a memory first data identifying the number of days of operation of the device required before a transducer head cleaning operation is to occur, storing in the memory second data identifying the number of days of operation since the last transducer head clean operation, storing in the memory third data identifying the number of transducer head cleaning operations that have been performed on the transducer heads, comparing the second data with the first data, displaying information suggesting that a transducer head clean operation be performed when the second data is equal to or greater than the first data, cleaning the transducer heads and printing the third data on a record member in response to the cleaning of the transducer heads.
