I think it must depend on the country. Down here the notes belong to the doctor, and any transfer of these is a courtesy (almost always done, and free of charge). The notes do not belong to the patient, although the information does. That means that if the patient would like copies of their notes they usually pay per page. The notes are sent directly from doctor to doctor, and not usually via the patient concerned.

Copies of notes at a public hospital, however, are available on written request, free of charge to the patient.
