There are ways to save memories without using a journal. I use a journal to get my thoughts on paper or send them to others who also have journals. Dealing with memories can be much more literal and they can be extracted from the mind just as they happened to be put away for safekeeping. As for journals and those who are blind, a wand can do many things, including working braille, dictation, and even having it read back to you. You do not necessarily need to empty the journal pages, but I do and prefer memory extraction to keep memories around.
