摘要： Provided is a magnetic recording medium. The magnetic recording medium includes a substrate, a recording layer disposed on the substrate for magnetic recording, and a carbon protection layer, which includes a carbon layer and a blocking layer disposed in the carbon layer to block infiltration of external impurities, disposed on the recording layer. Since the blocking layer is disposed in the carbon layer, a thickness of the carbon protection layer can be reduced while a sufficient hardness to protect the recording layer can be ensured, and moreover, a softness of the surface of the carbon protection layer can be improved.

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).
