摘要： The precedingly reproduction signal reproduced by a precedingly reproducing head is recorded on a tape. If it is detected that the reproduction signal includes abnormality owing to a reason such as poor error rate, the recording operation is stopped. Then, for retrial of the recording, the information on the position where the abnormality has occurred is held. A memory may be provided to always rewrite and store the signal reproduced by the precedingly reproducing head, and also a simultaneously reproducing head which is different from the precedingly reproducing head may be provided to immediately monitor the recording state of the signal recorded on the tape. If it is detected that the signal reproduced by the simultaneously reproducing head includes abnormality, the recording operation is stopped, the information on the position where the abnormality has occurred is held. Further, the rewrite operation in the memory is stopped and the original precedingly reproduction signal corresponding to the signal to be recorded at the position where the abnormality has occurred is held in the memory.

摘要： In a sensorless multiphase dc motor which is started by repeating a sequence of steps in order to supply the stator with a series of discrete currents for rotating the rotor in a desired direction, the start-up sequence has a step(s) of conducting a magnetizing shift action by changing the flow of current from one direction to the reverse direction or vice versa thus reducing its time consumption and also, each of the plural phase coils is energized with a high amplitude of current to produce a higher torque thus enhancing the start-up characteristics of the motor.In particular, the magnetizing shift action from one direction to the reverse direction or vice versa is conducted multiple times in each of the plural phase coils during the start-up sequence and the start-up sequence itself is repeated multiple times. As the result, the start-up characteristics of the motor will be more enhanced.
