Abstract:
Methods, apparatuses and systems for detecting defective sectors on a recording medium. A defective sector detector apparatus comprises an error-corrected ECC symbol number calculator and a defective sector determination unit. The error-corrected ECC symbol number calculator is configured to count a total number of error correcting code (“ECC”) symbols that are error-corrected in data read from data sectors on a track of a recording medium of the storage device. The defective sector determination unit is configured to receive the total number of ECC symbols that are error-corrected for a data sector from the error-corrected ECC symbol number calculator and determine whether the total number of ECC symbols that are error-corrected exceeds a threshold value. If it is determined that the total number of ECC symbols that are error-corrected exceeds the threshold value, the defective sector determination unit outputs information indicating the data sector to be a defective sector.

Claim (Index 15):
A storage device comprising:\n a recording medium comprising a plurality of tracks, each of the plurality of tracks comprising a plurality of data 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, the plurality of data sectors of a target track of the recording medium; and a memory containing code objects configured to cause the processor to\n write test data to the plurality of data sectors of the target track, \n read the test data from the plurality of data sectors of the target track, \n count a total number of error-corrected error correcting code (\u201cECC\u201d) symbols in the read of each of the plurality of data sectors, \n determine whether the total number of error-corrected ECC symbols of a data sector exceeds a first threshold value, and \n upon determining that the total number of error-corrected ECC symbols exceeds the first threshold value, determining the data sector to be a defective sector.
