摘要：
A method of producing a magnetic disk by lapping a magnetic disk medium, comprising the steps of: preparing a lapping tape having an abrasive particle layer provided with abrasive particle clusters and chip pockets formed between adjacent two clusters, each of said clusters having abrasive particles of Al.sub.2 O.sub.3 or SiC and abrasive particles of diamond, lapping the surface of said magnetic disk medium by using the thus prepared lapping tape.
