Double density and “flippy-floppies” are also on the horizon. A flippy-floppy allows data recording on both sides; regular floppies can use only one.

If the planet is on moderate eccentric orbit (0.01), it creates large-scale azimuthal assymetries which evolve at the orbital velocity of the corresponding resonance, for example at half time the planet velocity for the stronger resonance, the 2:1 one.
