OPTICAL INFORMATION RECORDING APPARATUS, OPTICAL INFORMATION REPRODUCING APPARATUS, AND OPTICAL INFORMATION RECORDING AND REPRODUCING APPARATUS

PROBLEM TO BE SOLVED: To downsize an optical information reproducing apparatus and an optical information recording and reproducing apparatus by making a pickup lighter in weight and making a driving means smaller in size, and to improve a transfer rate by making it possible to access the optical information recording medium at a high speed. SOLUTION: The optical information recording apparatus has a light source 32, an information expressing means 63 for forming information light by causing the light from the light source to carry the information, a reference light forming means 65 for forming reference light from the light from the light source and an objective lens 70 for irradiating the optical information recording medium 1 with the information light and the reference light and which utilizes a holography. The apparatus is equipped with a stationary section 73 including at least the information expressing means 63 and a moving section 75 including at least the objective lens 70 moving for the purpose of accessing to the prescribed recording position of the optical information recording medium 1.
