Production manner of origin board for patandomedeia and production manner of magnetic recording medium

摘要

Being production manner of the origin board for disk condition patandomedeia which is formed from the multiple sectors which are arrayed into circumferential direction, it included the servo data division and the record data division, with respect to process and the support substrate which form the imprint origin board where in the sector identification field of the servo data division before inserting the break in linear pattern, commonness lap the linear pattern which parallels to direction was formed at each sector, at least possesses the pattern of one sector, the imprint which uses the aforementioned imprint origin board the process which over again forms the pattern of patandomedeia of disk condition in circumferential direction and the pattern which was formed on the aforementioned support substrateInside, in linear pattern of the aforementioned each sector identification field, inserting the break in radial, the process which forms the pattern for sector identification and, it includes.
