3 EREI] TAPE ﬂEﬂK
The GX-ZGOD is the result of‘an extensive study to produce the best allvround tape deck possible within a reasonable
price range. A complete success, the GX-260D features Akai's world prized GX Heads for reverse recording and play-
back, and a unique center capstan drive system for friction-free tape travel and reduced wow and flutter. Put
the GX-ZGOD to any test you like. You'll find that it is completely unapproachable by any other make or model.

3 MOTOR DRIVE MECHANISM FOR
STABLE TAPE TRAVEL
This model employs Akai's unique and extra-
vagant self-lubricating type capstan drive motor
used only in highest quality machines. Two

Akai engineers are hard to please. They still wanted to produce a head which would
provide a wider than ordinary dynamic range and better high range frequency charac-
teristics, and, due to the superior characteristics of the head materials, they were able
to obtain an ideal surface shape for perfect head-to—tape contact as well as to obtain a
shallow gap depth for focusing the magnetic field into a sharp oblong radius. This
focused-field system minimizes high frequency loss, eliminates undue equalization, and
achieves a wider dynamic range. This amazing feature together with high quality general
engineering and the use of low noise tape enables the GX-ZGOD to exhibit an unbeliev-
able distortionless high freouencv range to 26,000Hz and a signal-to—noise ratio of 57 dB.

For watches and car engines, oil circulating self-lubricating motors
are more practical and lor audio motors as well.
To date, on constantly used machines, oiling was necessary every
six months. However, Akai’s new self-lubricating motor completely
banishes this bother. A motor capable of 10,000 hours oi operation
without oiling has become a reality! Further, the oil does not be-
come dirty and there is no oil eftlux. Devised for smooth non-varying
revolution: and tested for actual proof of phenomenal longevity,
this extraordinary motor also enhances the permanent characteristics
of the 6X Head, and fresh new sound is now your to enjoy hence-
Two separately installed oil circulating mechanisms.
The secret of this Akai developed Iongvlasting sell-lubricating motor
is the installation oi two oil circulating mechanisms with cellulose
fibers within the motor‘s interior. While the oil is circulating, shaft
revolutions are always smooth and stable. Oil circulating speed is
naturally adjusted according to motor revolutions and temperature,
and because the system is neither electrically or mechanically operated,
trouble resulting from oil circulating suspension does not occur.
Oil purified in cleaning process.
Unique cellulose fibers filter out the dirt while the oil is circulating
resulting in spotless oil for improved and lasting performance.
So important is the motor, that it is sometimes referred to as the
"heart" of a tape recorder. The superior capabilities of this motor
are not just first stage capabilities, but are completely maintained.
Thus. genuine appeal of new machine stereo sound Is yours to enjoy
