Emile Berliner, inventor of the disk record, proposed the idea to use a different method than the "hill-and-dale" method, which Edison used. "Edison made his sound records by causing the engraving tool to rise and fall, for which reason his medrhod is technically known as the "hill-and-dale". Berliner, on the other hand, thought it would be better to cause the tool to swing from side to side in the groove, for which reasson a disk was more serviceable than a cylinder. Because the tool moved side to side, Berliner records are called 'lateral cut'. Berliner's way of making the master record was also different. Instead of using an all-wax plate, he employed a disk of zinc, covered with wax" (Meadowcroft 7).
