IPC: G11C13/04
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To record more pieces of information in a hologram recording medium by making recording density high in a hologram recorder. SOLUTION: A reference beam R and an object beam O are reflected plural times inside the hologram recording medium 10, so that the beams R and O cross each other plural times inside the medium 10, and interference fringes generated at this time are recorded in the medium 10 as a hologram. Thus, the optical paths of the beams R and O inside the medium 10 can be long. Consequently, Bragg angle selecting performance and diffraction efficiency are improved similarly to the case that the thickness of the medium 10 is increased, so that the recording density can be made high.

As a result, the feed water pump 4 becomes a condition capable of being operated and an indicator 7 is driven into a low potential by a converting amplifier 97c whereby it is decided that the reserved water exists and a light (indication) is put off. At the same time, a relay 98 is operated to switch a relay contact 91 into OFF condition. This operation is effected instantaneously after the electrodes 81, 82 have detected the existence of water. Accordingly, the ionization of the electrode due to electrolysis can be avoided even when the electrodes 81, 82 are dipped into the reserved water successively.
