Abstract
1,228,307. Method of cutting a record. POLYBAND GES FUR TONTRAGER m.b.H. & CO. K.G. 25 March, 1969 [27 March, 1968], No. 15665/69. Heading G5R. In a method of cutting the record disc described in Specification 1,228,306, the cutting stylus is set to such a depth of cut relative to the lowest point of the mounted uncut disc surface, taking both wobble and irregularities into account, that the resulting sharp crests between grooves are located below the original disc surface. The cutter arm 106 is guided by shafts 120, 118 and driven across the record 111 by threaded shaft 119. These shafts are mounted in support members 116 and extensions 124 of these support members, support a further shaft 109 having a flat top 110 which co-operates with set-screw 108 to determine the depth of cut of the stylus 105.
