Abstract
For storing and retrieving data, the present invention enhances performance by allocating a single oversized contiguous storage area and by allowing data wrapping. Reliability is insured by verifying the coherence of stored variable length records at each READ operation. The coherence verification is optimized because the information required for verification, comprising a set of key values, is stored in the records themselves.
