Abstract: The present invention can record or reproduce information in a stable manner with a simple configuration. According to the present invention, since a photoinitiator whose vaporization temperature is between 140 and 400 deg C. is included, a portion around a focal point Fb of a recording optical beam L2c heats up after the recording optical beam L2c is focused, vaporizing the photoinitiator. As a result, an air bubble is formed. This air bubble is left in a recording layer 101 as a cavity after the emission of the recording optical beam L2c ends and the portion around the focal point Fb cools down. When a reading optical beam L2d is emitted, the air bubble can reflect the reading optical beam L2d due to the difference in refractive index between a portion inside the air bubble and the portion outside the air bubble (i.e. the recording layer 101), producing a returning optical beam L3.

Abstract: The present invention is to provide a method and an apparatus for mounting components having a feature of detecting with high accuracy component pick up failure by the nozzle at component pick up stage, and/or component carrying back by the nozzle at component mounting stage. Achieved vacuum pressure is initialized to zero after completion of component pick up by the nozzle 25, and vacuum pressure decrease of the nozzle 25 is detected from the initialized zero point. If the detected value is bigger than the predetermined threshold, it may be judged that at least one of the nozzles failed to pick up a component. The failed nozzle may be identified by using a component recognition device 37. Blowing air blow volume flowing through the nozzle 25 is measured upon completion of component mounting. If the blowing air flow is smaller that the predetermined threshold, it is judged that the nozzle 25 carries back a component 30.

The cycle time can be shortened, and eventually costs can be reduced.
