«One of the problems with OS/360 was that it supported many different file formats. The file system did not use fixed sized disc blocks, as the Titan had done, and as modern systems do. Instead, files were allocated as whole numbers of tracks, which the user program could fill with blocks of any size. Various ‘access methods’ were provided for reading and writing files in several different
formats. Unlike modern operating systems, where a file (as seen by a program) is just a stream of bytes, OS/360 files were read and written as records.»
