Film carriers for super-high-density magnetic storage

The problem of increasing the recording density in magnetic storage devices is considered. It is shown that nanograined magnetic film media are candid ate materials for magnetic data carriers. For these materials to completely meet the requirements for super-high-density magnetic carriers, appropriat e structure ordering must be set in the films. To this end, it is suggested to take advantage of the high adsorbability of 3d metal nanoparticles on h igh-molecular compounds. To produce the carriers based on these materials w ith a recording density of as high as 10(10) bit/cm(2) , nanoparticles of s ize less than or equal to 5 nm should be embedded in a polymer matrix. To d o this, it is necessary to combine chemical and physical methods for nanoco mposite production. (C) 2001 MAIK "Nauka/Interperiodica".
