发明名称 Magnetic recording apparatus and magnetic recording evaluating apparatus
摘要 A magnetic recording apparatus includes: a magnetic recording medium having a recording surface on which a plurality of magnetic recording cells magnetically isolated from each other are arranged; a magnetic writing element recording information to the magnetic recording cells under a condition in accordance with setting information; a magnetic reading element reproducing information recorded in the magnetic recording cells; a memory storing the setting information for writing; and a processor for executing a program code. The program code includes a test module, responsive to a test write start signal, for repeating writing and reading test information by the magnetic writing and reading elements and calculating a quality index value representing quality of writing of the reproduced test information with the setting information changed, and a write module for selecting setting information with which the quality index value satisfies a predetermined condition, and writing the selected information in the memory.
