Magnetic hard disc using spin valve heads |
| 摘要 |
The hard disc memory has a group of head units (18) having spin valve head elements (20) coupled to an IC circuit (14). This connects with a control circuit (12) that is based around a microcomputer (28) and provides overall control of the hard disc drive. The disc has an anti-magnetic layer, a pin layer, an magnetic layer a free layer. A test current produces a field that modifies conditions in the disc
