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

A method comprising steps of:

• calculating a servo gain for each servo sector of a track of a recording medium of a storage device;
• determining whether the servo gain of each servo sector exceeds a threshold value;
• and
• upon determining that the servo gain of a servo sector exceeds the threshold value, determining data sectors included in the servo sector to be defective sectors.

A storage device comprising:

• a recording medium comprising a plurality of tracks, each of the plurality of tracks comprising one or more servo sectors;
• a media interface which writes information to, or reads information from, the recording medium by accessing the recording medium;
• a processor which controls the media interface to write data to, or read data from, a target track of the recording medium;
• and
• a memory containing code objects configured to cause the processor to
• calculate a servo gain for each servo sector of the target track,
• determine whether the servo gain of each servo sector exceeds a threshold value, and
• upon determining that the servo gain of a servo sector exceeds the threshold value, determine data sectors included in the servo sector to be defective sectors.
