@grant_h@mastodon.social @altomare@oldbytes.space while this may have been true at one point, i regret to inform you that - if a read/write head was the size of a jumbo jet - it would be moving at about mach 1953 [or around 0.22% the speed of light] about 4 thou [which is around the width of a human hair] above the platonic ideal of a cornfield with almost preciously equally tall corn proof is below [i hope i didnt screw up my math cause that would make me look silly] keep in mind in this scenario the plane is essentially the disk as it is the one generating the primary rotational movement, of course this would require you to imagine the entire cornfield moving any time we actually want to use the actuator arm [now the actuation field] so yeah ive not done the math on retro hardware but for modern hardware its a bit different -carrie
