MAGNETIC DISK DEVICE

摘要

PURPOSE:To achieve a high-density assembly packaging with a high cooling efficiency and a superb assembly/maintenance properties by packaging a number of HDA's in one device in a simplified structure. CONSTITUTION:HDA 12 is mounted on HDU-BOX10 where a square tunnel structure is formed in units of four and the HDU-BOX 10 is mounted on a device in a configuration of two left and right rows and four upper and lower stages. A power supply 11 corresponding to the HDU-BOX 10 is provided on the downstream side from the cooling air channel of the HDA 12 and a fan for cooling is used commonly. The HDU-BOX10 and the power supply 11 become an expansion DKU90 in a pair and one to eight HDU-BOXes 10 can be mounted. A cable including a power-feeding cable to the expansion DKU is laid out vertically and is formed into a unit by a cable dust.
