Hi-MD and UMD?

I just read about Hi-MD. Are Sony's UMD (for the PSP) and Hi-MD two completely different formats or are they basically one and the same? (since Hi-MD comes in both 350Mb and 1Gb variants)

I think you're wrong.

Introduced by Sony in January 2004, Hi-MD is a nearly complete revamping of the original Minidisc system. The most significant change is the introduction of Hi-MD media, which includes a new 1GB blank in the existing MD form-factor and a reformatting of existing MD media that doubles its capacity to 305MB. In addition, several important and long wished-for Minidisc capabilities have been incorporated into Hi-MD equipment.

There is only one type of Hi-MD disc.
