Abstract

The read-out signal patterns by MAMMOS were classified and suitable read-out parameter (laser power, magnetic field) was estimated. By adjusting these parameters, both 0.2 micrometer size packed domain and modulated domains (T equals 0.2 micrometer) could be reproduced. The MAMMOS read-out from variously lengthened domains and eye pattern were obtained by application of a magnetic field synchronized with clock marks embossed on the disk.
