Zusammenfassung:	PURPOSE:To prevent a chip occurring at the front end part of a reproducing waveform by performing specific numerical restriction by changing the radius of curvature and the gap of a tape sliding plane. CONSTITUTION:The tape sliding plane 10A of a core chip 10 is formed in circular arc shape of top view, and assuming the radius of curvature as R and the gap(value in center in thickness direction) of each tape sliding plane 10A as W, they are set so as to satisfy such conditions as 19.5-20W
