Method and apparatus for increasing process yields of data storage devices |
摘要 |
Method and apparatus for increasing process yields of data storage devices which store data on media surfaces using read/write heads. An initial linear bit recording density is determined for each head, the linear bit recording density comprising a density at which each head is capable of writing data to and reading data from the corresponding media surface. Defective storage sectors are identified on the media surfaces to determine whether a sufficient number of logical storage sectors are available to meet a predetermined data storage capacity. The linear bit recording density of at least one of the heads is then altered to ensure that the storage device has sufficient logical storage sectors to meet the predetermined capacity.
