The IBM 3490E tape drive differs significantly from the 3480/3490 family. The 3490E uses 36 tracks instead of 18 and a thinner, longer medium. The 3490E can read 3480 tapes but can only write to newer 3480 tapes that are certified for use on a 3490E. Similarly, the Oracle StorageTek (STK) 4490 and 9490 36-track drives can read but not write to STK 4480 18-track tapes.
