If you go to Collection, you would notice that are 77 plates to unlock, but if you pay atention to the achievements, you can unlock only 10 of them. so... where are the 67 others?

the others are hidden. you need to clear 10 patterns from that song to get it. but... what is a pattern? what i need to do?

A pattern is what you play when you choose a song.

Let's pick, for example, "Secret Dejavu" 4 button mode. This are the difficultys this song have.



Each difficulty is a pattern. So, if we need to clear 10 patterns, we need to clear them from other buttons too. the thing is clear 10 patterns of the same song.

Keep in mind that SC patterns doesn't count to that 10, so you need to clear 10 patterns from Normal/Hard/Maximum only
EDIT: It looks like it counts too. I've unlocked Memoirs Plate with an SC chart (Normal/Hard/Maximum are 9 patterns in total)

There's some songs like Memory Of Beach that can't be unlocked like this. and if the song doesn't have 10 patterns, you're out of luck.
EDIT: Also, it looks like there are some songs that need less than 9 patterns, like chrono breakers

Here are some tips & tricks you can use:

• You don't need to clear them Full Combo/Perfect Play. you can clear them even with a C. the thing is clear the song, not making perfect score.
  
• You can clear them in Air Mode too

This are the songs that have hidden plates unlocked by patterns:

And this are the songs that can't be unlocked for now
