Latest Patents
Mizuma's latest patents include innovative designs for recording and playback apparatuses and optical heads. One of his key inventions involves a system where the light intensity of a beam emitted from a light source is controlled effectively. This system utilizes a variable optical coupling efficiency device, allowing the light beam to be transmitted with appropriate intensity. During the read mode, the light beam is incident on an optical disk at a weaker intensity compared to the light source. By switching the optical coupling efficiency between write and read modes, the light intensity directed to the optical recording medium is significantly varied. This arrangement eliminates the need for increasing the optical output power ratio of the light source between write and read power.
