Title:
MAGNET OPTICAL RECORDING MEDIUM
Document Type and Number:
Japanese Patent JPH04221446
Kind Code:
A
Abstract:
PURPOSE: To provide a magneto-optical recording disk having a high signal-to- noise ratio.
CONSTITUTION: This magnet optical recording medium consists of a substrate 52, a first dielectric layer 54, a recording section 56, a second dielectric layer 70 and a reflection layer 72. The recording section 56 contains plural pieces of magneto-optical recording layers 60 interposed with thin dielectric layers 63. The plural magneto-optical layers average magnetic transition errors and eventually improve the signal-to-noise ratio.
