Abstract
A method of manufacturing a prerecorded tape (9), the master taking the form of a helical pattern (13) on a cylinder (10). This cylinder (10) is rolled over a web-like intermediate carrier (1), the pattern (13) being replicated in strips (5) by a contact between the cylinder (10) and the intermediate carrier (1), which strips extend at an acute angle (.alpha.) relative to the longitudinal direction (3) of the intermediate carrier (1). The intermediate carrier (1) is cut along the strips (5) to form tapes (9).
