Abstract: An information storage apparatus includes a magnetic track, a writer, and a reader, where the magnetic track includes a number of magnetic domains. Each magnetic domain is divided into at least two magnetic regions, and the writer is disposed on the magnetic track, and configured to write information to the at least two magnetic regions of each magnetic domain. The reader, disposed on the magnetic track, is configured to read the written information from the at least two magnetic regions. Therefore, multiple pieces of valid information are written to one magnetic domain of the magnetic track, thereby increasing storage density of the magnetic track, and expanding a storage capacity of the storage apparatus.
