Abstract:
1. A system for processing a data read error from a tape medium, the system comprising: a reading section for reading data in data units from a tape medium; a reading control section for controlling said reading section to read data, and on condition that if an error occurs in reading one of said data units, the data unit where the error occurs is considered an error data unit and the reading control section issues an instruction to skip the error data unit and read the next readable data unit immediately after the error data unit; a computation section for computing a number of records and a number of boundary marks included in the error data unit where said error occurs from information about the records and boundary marks included in the data unit preceding the error data unit that is read immediately before said error occurs, and information about the records and boundary marks included in the data unit next to said error data unit, the boundary marks indicating the boundary of a record block; and a communication section for outputting the number information about said computed number of records and said computed number of boundary marks, wherein the information about the records and boundary marks included in the data unit preceding said error data unit includes the number of records and the number of boundary marks included in the data unit preceding said error data unit and the number of records and the number of boundary marks counted from the beginning of said tape medium to the data unit preceding said error data unit, and wherein the information about the records and boundary marks included in the data unit next to said error data unit includes the number of records and the number of boundary marks counted from the beginning of said tape medium to the error data unit where said error occurs.
