Description :
The Akai X-150D tape deck which adopted the crossing field head. A crossing field head is the first head for an Akai to succeed in utilization. Signal current is added to a recording head, bias current is made to be added to the outside head only for bias, and these heads are in the fixed space position shifted relatively. Therefore, even if it adds bias, the signal recorded on a tape does not receive the bad influence of a bias magnetic field, but is enabling faithful recording.
