Abstract
The efficient use of recording media in a magnetic recorder is the goal of advanced development efforts in longitudinal digital recording at RCA. The rotating head transverse scan (quadraplex) equipments utilized in broadcast television and wideband (4-15 mHz) instrumentation applications provide a prime example of the efficiency possible. The transverse scan equipments conforming to ASA standard C98.6 (1965) half track tape format record a 5.0 mil track with a 2.8 mil guardband which yields 128 tracks per inch of tape. When operating at 25 KBPI in-track packing density, these equipments obtain an area packing density of 3.2x106 bits per square inch. IRIG standard multi-track fixed head equipments conversely yield an area packing density of .07x106 bits per square inch when operating at the same 25 KBPI but only 28 tracks per inch.
