Method of performing read/write process on recording medium, parameter adjustment method, storage device, computer system, and storage medium employing the methods

A storage device comprising:

• a recording medium comprising a plurality of tracks that store data;
• a media interface that writes information to, or reads information from, the recording medium;
• and
• a processor that controls the media interface to write data to, or read data from, a target track of the recording medium,
• wherein, if a massive defective area in which a defect greater than a first set threshold measured in units of tracks is present in the recording medium, the first set threshold being set to a track length corresponding to a time needed for performing track switching on the recording medium, then the processor is configured to calculate a first parameter representing a logical track length of tracks included in the massive defective area by subtracting a length in a track-wise direction of the massive defective area from a physical track length of the tracks, the first parameter utilized in the reading and recording of information from the recording medium.

A method comprising:

• detecting that a track of a recording medium includes a defect greater than a first threshold, the defect occupying a defective area of the track;
• determining a length in a track-wise direction of the defective area;
• calculating a logical track length in the track-wise direction of the track by subtracting the length of the defective area from a total physical length in the track-wise direction of the track;
• assigning a logical block addressing scheme to the track wherein no logical addresses are assigned to any data sectors in the defective area;
• reading or writing to the track using the assigned logical block addressing scheme;
• switching a read/write head from the track to an adjacent track;
• and
• controlling the switching to start while a position of the read/write head corresponds to the defective area.
