Abstract
A tape cassette is set in a cassette accommodating section of a tape printer. A magnetically affixable printing tape is fed out from a holding reel along with an ink ribbon having a non-magnetic ink layer formed thereon across a cut in the tape cassette and conveyed through between a thermal head and a platen roller while being pressed by those elements. The printing tape comprises a printing layer and a magnetic layer pasted to the printing layer. The magnetic layer is magnetized such that S and N poles are alternately arranged longitudinally of the tape to thereby prevent turns of the tape roll from shifting widthwise. The magnetic layer has a coated fluorine layer formed thereon or has wrinkles formed thereon to thereby prevent blocking from occurring on a printing face of the tape due to its winding. Thus, the printing tape is conveyed in a correct attitude to enable a high quality image to be printed thereon.
