For a sealed case disposition you may either go to the clerk's office of the court that heard the case and request a copy in-person, or you may do so by writing.
If you request in writing, you'll need to write a signed and notarized letter to the clerk of the court location where the disposition occurred, and request a copy of your record.
Depending on the court there may be a nominal fee for the records ($5 or so per record).
