ENLARGED SUBSTRATE FOR MAGNETIC RECORDING MEDIUM |
| 摘要 |
An enlarged substrate for a magnetic recording medium used in a data storage device such as a hard disc drive (HDD). In some embodiments, an apparatus includes a substrate for a magnetic recording disc for installation in a 3½ inch form factor hard disc drive, the substrate having an overall diameter of nominally from 96.9 mm to 100.4 mm. In other embodiments, an apparatus comprises a substrate for a magnetic recording disc for installation in a 2½ inch form factor hard disc drive, the substrate having an overall diameter of nominally from 66.9 mm to 71.8 mm. In other embodiments, a data storage device has a magnetic recording medium that uses an enlarged substrate as set forth above. |
