A track seek control method of an HDD(Hard Disc Drive) and a recording medium suitable for the same are provided to embody stable track seek by automatically reflecting a shift in track seek although the shift occurs between discs and correcting the shift. Head switching is performed by using a head corresponding to a disc in which a target track exists(S702). A target track address is compared with a previous target track address, and a track seek distance is calculated(S704). It is judged whether the track seek distance is shorter than a limit seek distance set up in consideration of the shift of the disc(S706). If the track seek distance is shorter than the limit seek distance, a track address of a track on which the head is laid is read from the switched disc(S708). A track seek distance and a seek profile for the track seek distance are determined by referring to the read track address and the target track address(S710). Track seek is performed according to the determined seek profile(S712).
