Abstract

Performing read/write compatibility assurance is essential in computer systems utilizing multiple tape drives. The diagram illustrates a technique for performing compatibility assurance by minimizing the number of tape moves of a test reel. The operation is carried out under a program control which is suitable for use by a customer engineer or a system user. The program indicates which drive a scratch or test reel is to be loaded into. The program then records the address and sequence of each drive as the scratch reel is moved.
