Abstract: A method of determining a head characteristic, i.e. determining whether a head has a write characteristic stronger or weaker than that of a normal write head, and a recording medium suitable to perform the method. The method includes detecting a first error rate by writing data and then reading the written data without control pole tip protrusion (PTP) contralto compensate for thermal pole tip protrusion (TPTP) in a state where the head is fully cooled, detecting a second error rate by writing data and then reading the written data with the PTP control in the state where the head is fully cooled, calculating a difference between the first error rate and the second error rate, and determining based on the calculated error rate difference whether the head is a strong write head having a stronger write characteristic than that of the normal write head or a weak write head having a weaker write characteristic than that of the normal write head. Accordingly, since an adjacent track write (ATW) problem, which may occur due to a narrow gap between adjacent tracks, and a weak write problem, which may occur due to a short media recording length per data bit, can be simultaneously considered, high reliability can be secured in terms of recording and reproducing in an HDD.

Abstract: Optimal write current of a data storage device is determined by writing test data with an initial write condition and evaluating a performance related to the pole tip protrusion (PTP) of a magnetic head. A PTP control duration is determined as a duration between where the test data is initially written and where a performance evaluation value begins to satisfy a threshold criterion. An overshoot value of a PTP control signal that determines an overshoot amplitude of a write current and a PTP control duration are determined by for writing subsequent data such that PTP-related data errors are substantially constant regardless of write time.

Abstract: Provided is a handover method of a wireless communication system using a hierarchical cellular scheme. In the method, signal quality of a serving node is measured, so that whether to start scanning for a handover is determined. When the scanning for the handover starts, signal qualities of a serving cell including the serving node and one or more neighbor cells are measured through a first preamble including a first identifier for distinguishing a cell. An intra-cell handover or an inter-cell handover is selected using the signal qualities of the serving cell and the neighbor cells. Therefore, a terminal can easily distinguish between the inter-cell handover and the intra-cell handover, and an overhead during a handover can be reduced because an intra-cell handover procedure is simplified.
