Abstract
A computer implemented method includes obtaining positional information corresponding to end of data (EOD) on a tape and a data extent stored in the tape, wherein the positional information includes longitudinal position (LPOS), latitudinal position (wrap), and number of data blocks, comparing a block number of at least one of a currently read or located data with the positional information of the data extent to identify a current position of a tape head, identifying a positional relationship between a location of data to be read, the positional information of the EOD on the tape, and the current position of the tape head, identifying a directional relationship between a current direction of the tape head locating to data to be read and a pending write direction, and determining an appendable range for data after the EOD on the tape based on the identified positional relationship and the identified directional relationship.
