Abstract
We have developed a new MO(Magneto-Optical) disk, which is named iD(image/intelligent disk) PHOTO, as a promising candidate for a digital still camera memory. The iD PHOTO disk achieves 730MB/disk in a 50.8mm diameter by adopting some techniques mainly as follows, CAD (center aperture detection) type Magnetic Super Resolution reading, recording both on land and in groove, magnetic field modulation writing with irradiation of a pulsed laser beam, and PR(1,1) code. The iD PHOTO disk is required high performance in various environments, for it is used in a portable drive. As one of the most important factors, we have previously reported a reduction of electric power consumption by reducing the recording magnetic field. Here, we introduce thermal structure design of iD PHOTO disk to be suit for a drive in a digital still camera.
