Abstract
A digital recording/playback apparatus with improved error correction capability and a method thereof are provided. In the apparatus and method thereof, regardless of trick play data and stuffing data, normal play data is outer-error-corrected. To enhance the error correction capability of the normal play data, during a recording mode, a predetermined pattern data is arranged in the stuffing data region and trick play data region and an outer parity is added to the normal play data to then be outer-error-correction coded. During a playback mode, the predetermined pattern data used during error-correction coding is arranged in the stuffing data region and trick play data region and inner-error-correction decoded normal play data is outer-error-correction decoded using the outer parity.
