MAGNETIC TAPE RECORDING/REPRODUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To eliminate the influence of the wavy surface formed in machining on the lead step provided on the surface of the fixed cylinder to stabilize the tape run, in a magnetic tape recording/reproducing device to record and reproduce signals aslant on the magnetic tape by running and wrapping it around a rotating head cylinder consisting of a rotating cylinder and a fixed cylinder. SOLUTION: The running magnetic tape 5 is made to touch the lead step 6 only at two points, the position 9 the tape 5 starts to wrap around the rotating head cylinder 4 and the position 10 the tape 5 leaves the cylinder 4. And the middle 11 of the lead step 6 is kept off from the running tape 5.
