摘要： A method and apparatus for calibrating a position of an image sensor, and a method of detecting the position of an image sensor are provided. The method of calibrating the position of an image sensor includes: obtaining first image information corresponding to a first position of the image sensor and obtaining second image information corresponding to a second position of the image sensor, calculating cross-correlation values between the obtained first image information and second image information; determining whether or not the calculated cross-correlation values are symmetrical; setting a driving power value of the image sensor for moving the image sensor the distance between the first position to the second position as a reference driving power value for moving the image sensor one-pixel distance, if it is determined that the cross-correlation values are not symmetrical; and calibrating the position of the image sensor by using the set driving power value.

摘要： Provided is a method of increasing recording density and a control apparatus for increasing the recording density. The method includes applying a recording current corresponding to a recording signal to a magnetic head of a hard disc drive (HDD), and limiting a current value being applied to the magnetic head to a critical value when the recording current reaches the critical value. In the method, a rising time is reduced by using an overshoot recording current and the recording current is limited to a critical value when an actual recording current reaches the critical value. Thus, write track widths (WTWs) can be reduced at a low recording frequency, thereby increasing tracks per inch (TPI).

摘要： A method of recording bits on a ferroelectric medium using a scanning probe or a small conductive structure and a recording medium thereof, in which bit sizes can be decreased to increase data recording density as well as to reduce losses in reproduction signals. The method includes applying switching voltages to a lower electrode of the ferroelectric medium and the probe so as to write bits while approaching the probe to or bringing the probe into contact with a surface of the ferroelectric medium; and applying a base bias voltage, which is equal or smaller in magnitude and opposite in sign to the switching voltages between the switching voltages to make the probe equipotential with an upper portion of the record medium.

摘要： A data storage device using magnetic domain wall motion may include a first magnetic layer having a plurality of magnetic domains. A second magnetic layer may be connected to the first magnetic layer, and a connection layer may be disposed between the first and second magnetic layers. A resistive magnetic layer may be disposed between each of the first and second magnetic layers and the connection layer. Accordingly, when current is supplied to the data storage device to move a magnetic domain wall, the leakage of current in a connection between the magnetic layers may be reduced or prevented, thus conserving power.

摘要： A hard disk drive having a vibration reducing damper is disclosed. The hard disk drive is provided with a damper which is interposed between a through hole provided at a cover plate and a screw joined to the upper end of the shaft of a spindle motor, and includes at least one viscoelastic material layer. It is preferable that the damper has a multi-layered structure in which at least one high stiffness layer has relatively higher stiffness and at least one low stiffness layer made of a viscoelastic material has relatively lower stiffness. With the above configuration, the damper restrains vibrations generated by the spindle from being transferred to the cover plate, noises generated by the hard disk drive are reduced, and, in addition, since vibrations generated by the spindle motor are damped, disk fluttering is reduced.
