A laser -- actuated recording apparatus comprising:
- recording member supporting means for supporting a recording member;
- an ink holding unit including a plurality of recording head cartridges, a plurality of ink vessels containing inks, and a plurality of ink supply pipes detachably connecting said ink vessels to said recording head cartridges,
- said ink holding unit selectively locating one of said recording head cartridges at a position opposite to said recording member supporting means, and
- each of said recording head cartridges forming a layer of ink, supplied from a corresponding one of said ink vessels through a corresponding one of said ink supply pipes, on its opposing surface which is opposite to said recording member supporting means when it is located at the opposing position;
- and
- means for heating the layer of ink on the opposing surface of one of said recording head cartridges to generate a bubble in the layer of ink and causing the ink to fly from one of said recording head cartridges toward the recording member supported by said recording member supporting means by a pressure of the bubble.

A laser-actuated recording apparatus comprising:
- recording member supporting means for supporting a recording member;
- an ink holding unit including a plurality of recording head cartridges, a plurality of elastic ink cartridges detachably attached to one side surface of said recording head cartridges so as to cover the one side surface thereof and containing inks,
- said ink holding unit selectively locating one of said recording head cartridges at a position opposite to said recording member supporting means, so that the other side surface of the selected recording head cartridge, which is located at the opposing side of said head cartridge to one side surface thereof, faces the recording member supported by said recording member supporting means,
- each of said recording head cartridges forming a layer of ink, supplied from corresponding one of said elastic ink cartridges, on the other side surface thereof;
- and
- means for heating the layer of ink on the other side surface of one of said recording head cartridges to generate a bubble in the layer of ink and causing the ink to fly from one of said recording head cartridges toward the recording member supported by said recording member supporting means by a pressure of the bubble.
