The insulated makeup organizer includes three compartments in which the bottom compartment contains a coolant to keep makeup from melting. The first and second key strengths are different. The next step is then performed to control a positioner and a readwrite channel so as to start writing servo information onto a magnetic disk. The sensors are positioned with respect to the position of rest of the magnet in a specific manner in the main plane of symmetry of the magnetic field and near to extrema. The device also incorporates a method for maintaining DC current level during changes in digital filter characteristics.
