Title:
MAGNETIC TRANSFER DEVICE
Document Type and Number:
Japanese Patent JP3964299
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To continue magnetic transfer of high-definition by eliminating a main cause of deterioration of durability and defective transfer caused by dew condensation when magnetic transfer is performed while a master carrier and a slave medium are closely contacted to each other by using a holder.
SOLUTION: Master carriers 3, 4 carrying information and a slave medium 2 receiving transfer are housed in an internal space of a transfer holder 10 and closely contacted to each other, in performing magnetic transfer by applying a magnetic field for transfer, after magnetic transfer, when the internal space of the holder is opened to the atmosphere, dew condensation is prevented by keeping an atmospheric pressure dew point of the air contacting to the master carriers 3, 4 and the slave medium 2 to -10°C or less. Further, defective transfer is prevented by keeping particle diameter included in the air to 0.2μm or less. A filter dryer 15 exclusive for the holder is provided.
