THIN-FILM MAGNETIC RECORDING MEDIA

The continuing and very rapid growth in storage capacity in computer d isk drives is dependent on many factors, including continuing developm ents of the thin film magnetic recording medium. Following a very brie f description of a disk drive this review considers the various layers that make up the disk drive coating, with particular emphasis on the magnetic properties and microstructure of the storage layer. it also o utlines techniques used to fabricate and magnetically characterize dis ks and concludes with current ideas for future development of the tech nology.
