    Abstract: A method and apparatus to detect a defective sector include features of determining a first error value by counting the number of error symbols in first data read from a sector by using a head in an on-track state, and reading second data from the sector by off-tracking the head in a positive direction and third data from the sector by off-tracking the head in a negative direction in response to the first error value being equal to or greater than a first threshold value. Additionally, a second error value is determined based on the number of error symbols in the read second data and a third error value is determined based on the number of error symbols in the read third data. Accordingly, the sector is determined to have a defect by comparing an average of the second and third error values to a second threshold value.

    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: A method of forming a fine pattern of a semiconductor device using a fine pitch hard mask is provided. A first hard mask pattern including first line patterns formed on an etch target layer of a substrate with a first pitch is formed. A first layer including a top surface where a recess is formed between adjacent first line patterns is formed. A second hard mask pattern including second line patterns within the recess is formed. An anisotropic etching process is performed on the first layer using the first and the second line patterns as an etch mask. Another anisotropic etching process is performed on the etch target layer using the first and the second hard mask patterns as an etch mask.
