Abstract
A liquid jet recording method and apparatus for recording information on a recording medium. A laser beam is irradiated onto an opto-mechanical transducer provided at a position, in a liquid flow path having at its distal end a discharge orifice for ejecting liquid in a predetermined direction and a pressure acting zone, at which a pressure acts on the recording liquid filled in that portion of the flow path, where the pressure as generated is effectively transmitted to the recording liquid filled in the pressure acting zone. This enables the liquid to be ejected from the discharge orifice, by which laser beam irradiation mechanical displacement is caused to deform the wall of the pressure acting zone to thereby bring about abrupt pressure change in the liquid filled in the pressure acting zone to eject the liquid from the discharge orifice in the form of droplets which fly toward the surface of a recording medium, on which the droplets adhere to make a necessary recording.
