Cross-Field Head

On conventional recorders the signal and bias are applied to the same recording head. Therefore the frequencies recorded, especially the high frequency component of the recorded signal tend to be attenuated or erased by the effect of the bias field.

On the exclusive Akai Cross0Field Head which was developed by Akai for practical use the signal and bias heads are mounted in opposition with their centres slightly off. As the recorded signal is entirely unaffected by the prevailing effect of the entire frequency spectrum with maximum fidelity.

 

Sensing Tape Continuous Reverse

Automatic reverse with metallic sensing tape is used for playback only. Reverse operation will occur when metalic sensing tape on prerecorded tape makes contact with the Sensing PIN. Put metallic sensing tape as the desired reverse point on shiny side of the prerecorded tape and another metallic sensing tape at the desired reverse point  on dull side of the prerecorded tape. So, the M-10 will give continuous playback in both directions between two points
