Prior art Spin Valve Transistor (SVT) or Magnetic Tunnel Transistor (MTT) have two basic problems for the disk drive read head construction. One problem is that bottom magnetic shield used in read head not applicable to SVT or MTT as ferromagnetic layer underneath the semiconductor collector not desirable. Also semiconductor collector is very thick and therefore it is not possible to realize the narrow read gap.
