A polishing apparatus (1) includes a lapping tape (3) for polishing a surface of a magnetic disc (2), a tape supply unit (4) for supplying the lapping tape, a vamisher roller (5) for pressing the lapping tape (3) onto the surface of the magnetic disc (2), and a pressing unit (6) for pressing the lapping tape to the surface of the magnetic disc by way of the vamisher roller (5). The pressing unit (6) is constituted by a swing lever (51) having the varnisher roller (5) at one end portion, and a balance adjusting unit (52). The balance adjusting unit (52) sets the pressing force to zero by establishing the balance of the swing lever (51), and then breaks the balance so as to press the lapping tape to the surface of the magnetic disc by way of the varnisher roller with a desired pressing force. <IMAGE> |
