I don't know about IBM, but there was a 2nd generation Philco computer system (1401-era for IBM) that used 1-inch wide tape. My college used it for administrative functions back in the mid-1960's.

Re: IBM's first tape drive turns 60 (makes you feel old!)
One-inch tapes were once very common in IBM shops, and I will always associate them with a diversion. This width was of course incompatible with the half-inch one used for acoustical recording, but the magnetic-tape medium itself was not; and it was common, after regular business hours, to find computer-room tape drives being used to slit a one-inch tape into two half-inch ones. One enterprising operator friend of mine--He later became a sysprog who mostly lurks but sometimes posts here--even did a small business in selling slitters adapted to this purpose.
