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
