摘要
A single-sided magneto-optical (MO) disk with a thin substrate was previously studied in a stress-balanced disk in order to prevent disk deformation in a wide temperature and humidity range. We succeeded in the suppression of transitional disk tilt by developing new UV resins. Environment-proof mechanical characteristics to enable mobile use were satisfied for a high-density disk with a thin substrate, In this paper, we report that disk tilt within +/-0.5 mrad (+/-0.03 degree) was achieved in a 0.5-mm-thick and 50-mm-diameter disk.
