For the rotating optical head of an optical tape recorder, whose optics are divided into a fixed part and a rotating part, and whose beam is controlled with a lens in the fixed part, the focusing operation causes a change of both the diameter of the incident beam to an objective lens and the optical magnification. Therefore, we developed an optical system which does not cause these changes and confirmed stable focused-spot characteristics for a ±60 μm displacement of the recording medium by carrying out recording experiments.
