A transducing head for a magnetic tape recorder comprises a first magnetic pole and a second magnetic pole positioned to form a gap therebetween. In one embodiment, a point-to-multipoint LSP is built in a MPLS network by using Resource Reservation Protocol Traffic Engineering to signal the point-to-multipoint LSP as separate point-to-point LSPs and to merge the separate point-to-point LSPs into the point-to-multipoint LSP. The photoresist film 15 after the development has a first photoresist film 16 and a second photoresist film 17 that is thicker than the first photoresist film 16. The first three linkage assembly maintains the orientation of the vehicle relative to the wheel during the lifting and lowering while the second linkage assembly provides the power to lift and lower the vehicle.
