In a recording apparatus using a plurality of kinds of head cartridges each comprising an ink jet recording head and an ink tank formed as a unit, the present invention prevents, when a wrong head cartridge has been mounted during cartridge exchange, data regarding the remain of ink in a thitherto used cartridge of other kind from being lost, and enables the remain of ink in that cartridge to be confirmed. A user is pressed for the exchange of the head cartridge now mounted to thereby effect the exchange actually, and is called on to confirm whether the newly mounted head cartridge is a right one, and the initialization of the data regarding the remain of ink is effected when the user has done the inputting of the confirmation.
