PROBLEM TO BE SOLVED: To improve the performance of cooling a plurality of magnetic disk memories as an aspect.SOLUTION: A plurality of magnetic disk memories 16 each have: a printed circuit board 24; a magnetic disk 26; and a case 28. The magnetic disk memories 16 are spaced from each other in a thickness direction of the printed circuit boards 24. Fans 18 form the cooling air flow 32 flowing through the spaces between the magnetic disk memories 16. Each printed circuit board 24 has a projection 30 that projects toward the case 28 in a height direction of the magnetic disk memories 16. A space 34 between respective projections 30 of each adjacent pair of magnetic disk memories 16 is wider than a space 36 between the case 28 and the printed circuit board 24 of each adjacent pair of magnetic disk memories 16. In each space 34, electronic components 38 mounted on the projections 30 are arranged. |
