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.
