The mechanism of damage is different. The faulty disks aren't vibrating the drive to death, the drive is head-banging[0]. Iomega cost-reduced the drives to a fault; removing a tiny piece of foam that is there specifically so that head-banging doesn't damage the drive head.
Head-banging is an intentional feature on disk drives[1] to correct for read errors and get back to a known good state; so a corrupted disk would cause it to head-bang every time you tried to read from it. And since there was no cushioning on the drive rails each head-bang would misalign the drive... making it corrupt more disks!
I'm not sure what the record player equivalent to this would even be. A very heavy stylus could damage the disc and carve into it, but there's no way you could have a disc permanently change the tracking weight of that stylus.
[0] When a disk drive intentionally crashes its head against a mechanical limit to ensure position of that head in lieu of having an actual sensor
[1] The most egregious case being the Apple ]['s 5 1/2" drives, which intentionally do this on every power-up.

A very heavy stylus could damage the disc and carve into it, but there's no way you could have a disc permanently change the tracking weight of that stylus. Conceptually, you could have a record made of "tar", which got scraped off onto the stylus and was then impossible to clean off.
