Cushioning material and information storage device using the same

A cushioning material for supporting an inner first housing and an outer second housing to have a distance between said first and second housings, comprising:

• a main body having a space to come in contact with an outer surface of said first housing to cover at least part of said first housing;
• a contact surface formed on an outer surface of said cushioning material to come in contact with an inner surface of said second housing;
• and
• a hole formed in at least part of said contact surface to promote deformation.

An information storage device removably mounted on a device body, comprising:

• a hard disk driving mechanism;
• a first housing for accommodating said hard disk driving mechanism therein;
• a second housing for accommodating said first housing therein;
• and
• a connector portion,
• wherein said first housing is supported by a cushioning material to have a distance between said first housing and said second housing,
• said cushioning material has a main body having a space to come in contact with an outer surface of said first housing to cover at least part of said first housing, said first housing being and has at least one projection portion formed to protrude from said main body toward said second housing, and
• said projection portion has a contact surface to come in contact with an inner surface of said second housing, said contact surface being formed to extend along said inner surface.
