Cross-Field Head
On conventional
recorders the signal and biass 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 this bias
field. On the exclusive Akai Cross-Filed 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 unaffacted by the
prevailing effect of the bias fielf, the tape can be recorded over the entire
frequency spectrum with maximum fidelity.
One Micron Gap head
Model X-1800SD
utilizes the cross-field head to obtain an amazing level of recording
characteristics in reel-to-reel recording. In cartridge recording, the
high-quality one micron gap head designed by Akai also gives excellent
recording characteristics. This recording characteristic, 50 to 17,000 Hz ±3 dB
at a tape speed of 3-3/4 ips, produces excellent results for cartridge tape
recordings.
8-track stereo
recording/playback (cartridge)
Model X-1800SD
employs the 8 track stereo system on the cartridge. The tape has a total of
eight tracks, two of which are used at a time for stereo recording or playback.
These are four choices of channels for stereo recording and playback. When the
tape ends, the next channel is automatically positioned for recording or
playback. Recording or playback time for one channel is fifteen minutes, and
continous one hour on four channels by using 300 foot cartridge tape. The
desired channel may be easily selected by manually pushing the Cartridge
program Selector Button.
Cartridge recording
tape (ACT-200, ACT-300)
Akai's 1800 series
tape recorders, Model 1800L and X-1800SD are the latest models that are capable
of recording with a cartridge tape. For use in this type of recording, we have
cartridge recording tapes, ACT-200 with 200 foot long tape, and ACT-300 with
300 foot long tape. This cartridge tapes are highly recommended for best
results.
