The IBM 3740 format of 8" floppy disks was used in the 1970s IBM 3740 data entry system, which replaced keypunch systems that stored data on punched cards.
The disk format was single-sided, single-density, and had 73 tracks with 26 sectors storing 128 bytes per sector. The total capacity was 237.25 KB. FM encoding was used.
