    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.
