Abstract

See full text

A request for writing a first index information to a first partition of a serial storage medium of a serial system is received. The serial storage medium includes a first partition for writing the first index information including a first index position, a second partition for storing a data set, the data set including a second index information including a second index position, a memory for determining the second index position, and a module for writing the first index position. A beginning position of the first index is written on the first partition. A determination is made whether the beginning of the first index position is proximate to the second index position. In response to the beginning of the first index position being proximate to the second index position, an interrupted index position is registered. A dummy index is written to the first partition at the interrupted index position.
