Summary :

The Dynamic Readout performance of a micro-optical head, consisting of a semiconductor laser on a flying slider and a glass substrate disk medium has been examined. An antireflection coated (ARC) laser diode, whose reflectivity facing a medium, is less than 5%, is useful in decreasing signal amplitude fluctuation due to the head-to-medium spacing.
