What is the record for the most #1 album debuts in a row?

This is from a British website:

Two groups have had unbroken runs of 8 chart-toppers. They are Led Zeppelin (from "Led Zeppelin 2" in 1969 to "In Through The Out Door" in 1979) and Abba (from "Greatest Hits" in 1976 to "The Singles - The First Ten Years" in 1982). By an odd piece of synchronicity Led Zep's eighth consecutive chart-topper ("In Through The out Door") was recorded at Abba's very own Polar Studios in Sweden.

Leading soloist is Robbie Williams (5 - from "Life Thru A Lens" in 1997 to "Escapology" in 2002). Leading female soloists with 3 consecutive number ones each are Eva Cassidy (from "Songbird" in 2001 to "American Tune" in 2003) and Madonna ("Evita" 1996 to "Music" in 2000, though "Evita" was a soundtrack album featuring a number of other artists).

The Beatles
