Fun facts
This format can be distinguished from the other 1" types by the way the tape wound, with the oxide facing out instead of in; Type C tape would face in and Type A could be either if created before 1975
This format segments each field to 5 (NTSC) or 6 (PAL) helical scan tracks per field, instead of recording one field per track
This format began to replace 2" Quad and 1" Type A, but it was later largely replaced by 1" Type C for use in broadcast television
