Description
MIR Disk Read/Write Head DAS Device 110-117C Rev G G16503-2 RK18226C
This is a MIR disk read/write head assembly, part number 110-117C (Revision G), a DAS (Disk Access Sensor) type device built on a rectangular blue PCB. The assembly features a large circular radial gold-trace contact array centered on the board, with a precision cross-aperture read/write head element at its center and a dense multi-track flat ribbon trace field running along the length of the board. A secondary circular gear-ring contact pad surrounds the central head element. The board carries part numbers G16503-2 and RK18226C and is marked Rev G.

Applications
Disk read/write head assemblies of this type are precision electromechanical components used in magnetic disk storage systems to read and write data on rotating magnetic media. The radial multi-track contact array design is characteristic of heads used in specialized data acquisition storage (DAS) systems, instrumentation recorders, or high-track-count disk drives found in scientific, industrial, and aerospace data recording applications. The dense gold-trace PCB layout and numbered contact pads (extending into the 80s) suggest this is a high-channel-count device designed for systems requiring simultaneous multi-track data access — common in flight data recorders, seismic recording systems, and industrial data logging equipment from the late 1980s through the 1990s. Replacement heads of this type are sought by facilities maintaining legacy disk-based data recording systems where the original head has worn or failed.
This MIR Disk Read/Write Head DAS Device (110-117C Rev G) is new and unused. It is being sold as open box — the item is new but may not be in its original manufacturer packaging. The central disk head element is visible in a protective plastic bag on the PCB assembly, consistent with a new, uninstalled component. No signs of use, wear, or damage are visible.
