Patent ID: 7626800

Claim:
A bulk erase tool for erasing perpendicularly recorded media on a hard disk drive comprising: a first polarity erase magnet; a second polarity erase magnet offset from said first polarity erase magnet, wherein said offset between said first polarity erase magnet and said second polarity erase magnet produces a non-parallel non-vertical applied field utilized for erasing perpendicularly recorded media on said hard disk drive without demagnetizing a motor magnet of said hard disk drive; and a flux guiding mechanism for redirecting said non-parallel non-vertical applied field, said flux guide mechanism comprising: a magnetic material formed in an approximate shape of an “L” for redirecting said flux to provide a location of protection for a motor magnet of a hard disk drive, when said hard disk drive is inserted into said applied field of said bulk erase tool.
