Magnetic field sensor using heterojunction bipolar transistors |
| abstract |
A magnetic sensor using heterojunction transistors for detecting magnetically recorded data. The sensor has a pair of heterojunction transistors T1, T2 connected in a differential circuit disposed on a substrate 18. The substrate 18 is carded on the free end of a suspension arm 12 at a distance D from the surface of a disk 14 having magnetically recorded data thereon. The transistors are disposed a distance S apart which is selected with D so that the magnetic field direction at one transistor is generally perpendicular to the disk 14 and the magnetic field direction at the other transistor is generally parallel to the disk 14 when a magnetic transition occurs immediately adjacent the magnetic sensor. |
