title = "Mathematical model of multiactuator for HDD head positioning system",
abstract = "The development of hard disc drives illustrates well the increase of data areal density, which in 1995 had/was about 1Gb/in2, in 2010-400Gb/in2, at present it reaches 1-1.5 Tb/in2. The article will present a mathematical model of the modern multiactuator for the head positioning system. This actuator, intentionally modified, will have several armature windings and an especially designed excitation system in the form of a multi-layer permanent magnets assembly. This actuator designed for the positioning system allows us to build a branched positioning system (in which several heads will be moved over the data discs in an independent way). Application of such an actuator in head positioning systems can reduce the access time to data several times. The result of field calculation is presented, the mutual interactions between armature windings are examined, and finally the mathematical model of the multiactuator in terms of an ordinary differential equation is given. The proposed mathematical model allows to design new control systems of multiactuator.",
