C.3.2 Other Media

For fixed block length sequential media where the physical block size cannot be equal to or an integral multiple of the standard FITS logical record length, a logical record of fewer than 23040 bits (2880 8-bit bytes) immediately following the end of the  primary header, data, or an extension  should be treated as an end-of-file. Otherwise, individual FITS files should be terminated by a delimiter appropriate to the medium, analogous to the tape end-of-file mark. If more than one FITS file appears on a physical structure, the appropriate end-of-file indicator should immediately precede the start of the primary headers of all files after the first.
