摘要： A control circuit of a voice coil motor is configured to move at least one read/write head of an hard disk into a parking position. The control circuit compares a received supply signal with a reference signal having a minimum value and a maximum value and a frequency. When the value of the supply signal is between the minimum value and the maximum value of the reference signal, the controller causes alternation of a working condition of the voice coil motor, when the value of said supply signal is higher than the value of the reference signal, and of a stop condition of the voice coil motor, when the value of said supply signal is lower than the value of the reference signal, with a frequency equal to the frequency of said reference signal.

摘要： A control method of the magnetic actuator system includes the following steps. A first initial orientation step is to move a magnetic actuator to a first position in accordance with a first position signal, and generate a first position sense signal by a position sensor. A second initial orientation step is to move the magnetic actuator to a second position in accordance with a second position signal, and generate a second position sense signal by the position sensor. An orientation step is to perform an interpolation in accordance with the above signals and a target position signal to obtain a target position sense signal. A moving step is to move the magnetic actuator to an actual position in accordance with the target position signal, and output an actual position sense signal by the position sensor. An adjustment step is to move the magnetic actuator to a target position in accordance with the target position sense signal and the actual position sense signal.

摘要： A magnetic storage medium is formed of magnetic nanoparticles that are encapsulated within carbon nanotubes, which are arranged in a substrate to facilitate the reading and writing of information by a read/write head. The substrate may be flexible or rigid. Information is stored on the magnetic nanoparticles via the read/write head of a storage device. These magnetic nanoparticles are arranged into data tracks to store information through encapsulation within the carbon nanotubes. As carbon nanotubes are bendable, the carbon nanotubes may be arranged on flexible or rigid substrates, such as a polymer tape or disk for flexible media, or a glass substrate for rigid disk. A polymer may assist holding the nano-particle filled carbon-tubes to the substrate.
