Suggested Generic Standard for SEGY Files of Stacked Data

Although the SEC standard for SECY does not apply to stacked data, stacks have been stored on tape media for quite some time in a format roughly following the SEC publication. For tape media, the EBCDIC, the binary file header, and individual traces (single trace blocks) are put on tape, each separated by an inter-record gap and then followed by a single EOF. Several lines may be stored on tape in the above sequence with one EOF between lines and two EOFs after the last line. Subsequent tapes in multi-tape volumes should have EBCDIC and binary headers at the start of each tape.
