Abstract
A recording head protective overlay arrangement with an alarm capability is provided. The protective overlay is continuously replenishable between the recording surface of the recording head and the recording medium and is movable in a direction opposite to that of the recording medium so as to provide a cleaning function as well as a wear-preventive function. A dispenser cartridge housing the protective overlay is provided which is specially designed to closely conform to the recording head. A pivotable cartridge holder is included for enabling the cartridge to be inserted in a position remote from the recording head and pivotable into an operative position with the recording head. The tape medium itself and various components operatively associated therewith are pivotably mounted, to provide movement of the medium into intimate operative contact with the overlay and the recording head.
