A drive housing (22) for shielding a storage disk (13) and a data
transducer (48) of a disk drive (10) from external magnetic fields
includes a housing shield (24) positioned near the storage disk (13). The
housing shield (24) includes a base shield portion (60) and a cover
shield portion (64) that are positioned substantially parallel to the
storage disk (13). The housing shield (24) also includes one or more wall
shield portions (62) oriented substantially perpendicular to the storage
disk (13). The housing shield (24) is uniquely sized, shaped and formed
from material to have an attenuation of field of at least approximately
10 dB. With this design, the influence of external magnetic fields is
reduced and the incidence of damage to data stored on the storage disk
(13) is reduced. Additionally, the housing shield (24) enhances the
accurate transfer of information between the storage disk (13) and the
data transducer (48) of the disk drive (10).
