WRITE-ONCE ZINC OXIDE NEAR FIELD OPTICAL DISK

Title:

WRITE-ONCE ZINC OXIDE NEAR FIELD OPTICAL DISK

Document Type and Number:

Japanese Patent JP2003346380

Kind Code:

A

Abstract:

To provide a write-once zinc oxide near field optical disk that its zinc oxide nanofilm layer generating a local near field optical effect can make ultra-high density near field optical recording within the range of the near field optical effect on a recordable recording thin film layer.

The write-once zinc oxide near field optical disk consists of a transparent substrate 1 and a plurality of thin film layers on a transparent substrate 1. These thin film layers comprises a zinc oxide nanofilm layer 3 generating a local near field optical effect, a write-once recording layer 5, and first, second, and third transparent dielectric thin film layers 2, 4, 6 to protect and maintain the whole thin film structure properties.
