What I do not understand yet since the floppy drive days is this: If HD controllers are blinding ASIC-fast, why can’t we have three 120-degree actuator arms, or 4 arms, 5?. Or even a radial axis of 120 piston-like actuator arms full of magnetic read heads. We have obviously nailed the head-of-line queueing, the quality-of-service queue, the anti-quantum tracking guidepost, the ability for N-head on same track, the constant density per orbital track, the buffeting airflow magnetic head reader (via semi-vacuum enclosure), the thermal drift/expansion, and the anti-shock advantage of its radial piston arm’s magnetic read head not “buying the farm” over sweep arm. It isn’t about the sweeping arc of the actuator arm anymore. You can now have piston-like (albiet slower) actuator arms but the sheer number of radial axis piston-actuator should make for faster read retrieval and maybe write as well … than SSD? Heck, we make printer heads with interval thinner than its paper, 1,024 Cochlear implant point probes over millimeter span, surely a multiple non-moving radial axis of flying scanning multi-million read heads can be floating across the entire platter? (A fixed platter silicon chip of read heads floating on top of a spinning magnetic platter?) Of course, this is just me, the armchair quarterback of floppy drives and thinker of cross-domain technology. Please be kind.
