sorry i didn't even think to ask my roomate. he basically just said it's newer technology. that "longitudial" (poor spelling ik) takes up more space on a disk.
so basically w/ perpindicular recording it uses up less space on a disk and therefore can fit more GB on the same size of disk.
sorry for posting a topic that i didn't need to. i'm retarded lol.
