High capacity MO media for digital still cameras "iD photo"

Abstract

A magneto-optical disk system, named iD (intelligent, image) photo disk has been developed as a next generation media for digital still cameras. It has a large recording capacity, 730 MB with a 50.8 mm diameter. It employs the field modulation method for recording and center aperture detection (CAD) type magnetic super resolution for reproducing. The media is designed to decrease the recording field so as to reduce electric power consumption for mobile use.
