Patent JP-S6168792-A (JP)
Title: Magnetic disc device
Inventor: HATTORI SHUNSUKE
IPC: G11B33/14
Filed: 1984-09-11
Abstract: PURPOSE:To absorb water content in air in the titled device with very simple constitution by arranging a block made of a moisture permeable material including a moisture absorbing agent to a proper place in the device. CONSTITUTION:The moisture absorbing agent 10 is impregnated to the block 9 made of silicon rubber or polyurethane resin. There is a gap to pass through water moleculars in the molecular structure of the block 9 but particles with a particle diameter of >=0.1mum disturbing stable floating of a slider are not transmitted and the inside of the block is kept dry. Then water vapor increasing the humidity of the outside of the block is absorbed into the block. Thus, the water content in the device is absorbed with very simple constitution without any provision of a filter.
