OVERWRITE IN PARTICULATE TAPE MEDIA

Overwrite in particulate tape media is studied utilizing a micromagnet ic simulation model, Seven different media, including traditional thic k tape and thin metal-particle tape, are simulated to study the effect of tape thickness and demagnetizing ratio on overwrite, Recording hea d parameters, such as the record gap, the record current, and head-med ium spacing, are analyzed for overwrite in the thick tape media, An an alytical formula is developed to describe the overwrite ratio as a fun ction of the frequency ratio before and after overwrite.
