Abstract
A method and apparatus for storing user data organized into a plurality of data records on tape is provided. User data is first accepted from a host computer. The user data is then organized into data groups independent of the record structure. Records are then assigned to data entities where each data entity has at least one data record. A group index is formed to which information pertaining to the records and/or entities contained within the group is written. Data is then stored on the tape in groups along with each associated group index.
