讨论了磁光(MO)盘中的读出。从读出品质因数的观点出发，提出了具有横向、纵向和极向克尔效应的钼信号。对比是在有或没有垂直磁化的材料中进行的，包括对光束入射角的依赖关系。尽管入射角必须很大，但在415 nm波长下，PtMnSb在横向克尔读出中比TbFeCo在极克尔读出中提供更大的优值因子。>；
Readout in magnetooptical (MO) disk is discussed. MO signals obtained with transverse, longitudinal and polar Kerr effects are proposed from the viewpoint of the figure of merit of readout. The comparison was done in materials with or without perpendicular magnetization, and included the dependencies on the incident angle of the beam. Although the incident angle must be large, PtMnSb gives larger figure of merit in transverse Kerr readout than TbFeCo in polar Kerr readout at a wavelength of 415 nm. >
