The features of codeposition process of Ni, Ni-Fe, Co-P, Co-Fe-P, Ni-P, Ni, and Cu matrixes with ultra dispersed diamond particles from sulphate, chloride, acetate, glycine, citrate, sulphamate bath were investigated in view of magnetic recording systems application. The cation and anion surfactants were used to study the liophobic colloid systems and the behavior of ultra fine particles, to prevent agglomeration and sedimentation and to control the particle incorporation into metal matrix. Mechanical properties of composite films were described from the point of view of applications in high-tech devices. It was determined that wear resistance increased 2-2.5 times, microhardness increased 2 times, coefficient of friction and corrosion current were reduced by factor 1.5 and 1.6 respectively. Application of nanodiamond particles in technology of composite functional layers of hard disks, magnetic heads, micromotors, and micromechanical components allows increasing reliability of storage information systems considerably.
