Abstract: For determining an access sequence of a plurality of data groups stored on a tape medium, a first data group in the access sequence is selected based on which data group in the plurality of data groups has a beginning closest to a current position of the tape medium. A second data group in the access sequence is selected based on which remaining data group in the plurality of data groups has a beginning closest to an end of the first data group in the access sequence.

Abstract: An information recording apparatus includes a writing system for writing the datasets to the recording medium, so that each of the datasets can be identified from a certain number indicating an order that each of the datasets was sequentially written to the recording medium, and from the number of writing operations (WP) carried out for a dataset of the certain number, the writing system writing a first dataset; the writing system being configured for substantially appending a second dataset onto the first dataset, the second dataset having the same certain number as the first dataset, and for setting a value obtained by incrementing the WP of the first dataset as the WP of the second dataset.

Abstract: In a controller of a tape drive, a CM input-output unit recognizes a tape format; a tape variable acquisition unit acquires tape variables; a setting variable acquisition unit acquires setting variables; and a minimum number calculator calculates a minimum number m of sub datasets, which are to be written to a tape to secure resistance to burst error, by using the tape variables and setting variables. When a command processor receives a synchronization command, the buffer manager generates n sub datasets for storing data in the buffer. If n is smaller than m, m sub datasets are padded out and set as write data. If n is m or more, the n sub datasets are set as write data. Then, the channel input-output unit writes the write data to the tape.
