Abstract
A method of recording and/or playing back a data signal, in an apparatus in which a tape helically encircles a drum containing a headwheel, and the heads scan oblique tracks on the tape, features reduction of the tape velocity by a factor 1/n where n is a positive integer. Along with the tape velocity change, the static tracking angle between the tape and drum is correspondingly adjusted so that the heads will continue to scan along a standard track pattern or format. The data rate of data signals retrieved from the tape (e.g. high-date rate satellite transmissions) or of incoming data signals can be converted to a different data rate by intermediate steps of writing to a digital memory and reading back at a more desirable data rate.
