Strange peripherals… the Triton Quick Disk

TritonQD_thumbWhen it comes to disk drives, most of us will have used the 1541 or the 1571 with our trusty C64/C128. If you were lucky, you could have been one of the few to have actually owned a 1581 back in the day and used it with the smaller and sturdier 3.5” disks.

But if you really wanted something exotic as a disk drive, then the Triton Quick Disk might have been something to consider.
In the mid-80s a 2.8” floppy disk drive, the Triton Disk Drive, was introduced by Radofin Electronics, Ltd.
Next to compatibility with the breadbox, it worked just as well with the other popular home computers of the time (ZX Spectrum, MSX, …).
This compatibility was achieved by means of an operating system stored on an EPROM on an external controller that came included in the package.


What made this floppy system special is that the Triton combined the floppy disk rotation with a continuous linear tracking of the head and hence created a single spiral track along the disk similar to a record groove. This was in contrast to the traditional disk drive where individual tracks were be accessed by positioning the read/write head with the step motor.


The “spiral” was completed within eight seconds which meant that consecutive access time was restricted to eight seconds and that formatting a disk became extremely fast.

The Quick Disk could hold up to 100 Kbytes of data and had a transfer rate of 101.6 Kbits/sec which made it a very fast drive for the day… and for the price.
The whole system would only set you back for roughly 150 Euro – a decent price for a decent piece of equipment.

  1. two days ago i bought an exotic disk drive for my AKAI S612 sampler.
    the funny things is the disk drive uses 2.8 quick disks and is produced by Akai. i wonder if the Triton Disk Drive and the Akai MD280 drive are identical / compatible.

    here is how the Akai drive looks like:

    That looks like an interesting piece of equipment there! The drive’s perhaps not 100% compatible, but the disks are. Next to the Triton Drive, the 2.8 disks were also (commonly) used in various MIDI samplers and keyboards.

    This is also the format used by the semi-obscure Famicom Disk System (kind of a disk drive for the japanese NES The game disks where customized with a engraved “Nintendo” block that has to match one inside the drive.

    I have one, and every access lasts seven seconds, and reads all the disk :)
