Summary: | The present invention provides a technique for detecting a defect in a tape medium within a relatively short or narrow range. A tape defect detection device includes: a read unit for reading data from a tape medium; an error correction unit for performing error corrections for the data read by the read unit; a correction number counting unit for counting the number of the error corrections, made by the error correction unit, for each of multiple divided areas of the tape medium; a temporary storage unit for temporarily storing, for each of the areas, the number of the error corrections counted by the correction number counting unit; and a detection unit for detecting a defect in the tape medium, on the basis of a distribution of divided areas each having a larger number of error corrections than other divided areas on the tape medium. |
