This 8-inch disk unit was marketed as an OEM disk unit for office computer manufacturers.
Since the unit employed a voice coil motor system as a head positioning mechanism, instead of the previous step motor, seek time was greatly increased to 25ms.
The HDA (Head Disk Assembly) had a completely sealed structure, and thus had outstanding environmental resistance and required no periodic maintenance.
