Abstract
Signal quality in an optical storage device greatly depends on the optical system transfer function used to write and read data patterns. The problem is similar to analysis of scanning optical microscopes. Hopkins (1) and Braat (2) have analyzed write-once-read-many (WORM) optical data storage devices. In this paper, we discuss transferfunction analysis of magnetooptic (MO) data storage devices with respect to improving transfer-function characteristics. Several authors (3)(4)(5) have described improving the transfer function as super resolution. However, none have thoroughly analyzed the MO optical system and effects of the medium. In our development, we discuss both the optical system transfer function and effects of the medium.
