Abstract: A magnetic disk drive includes a base having an opening, a cover configured to close the opening of the base, and a pressure-sensitive adhesive sheet configured to seal a gap between the base and the cover. The pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer, and a substrate layer configured to support the pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer has a storage modulus of 250 kPa or less at 23° C. The substrate layer has an elastic modulus of 1,680 N/cm to 3,000 N/cm. The pressure-sensitive adhesive sheet shows a deviation amount less than 1.0 mm, the amount being the deviation amount of the pressure-sensitive adhesive sheet per 250 gf/cm2 of the sheet in a holding ability test at 80° C. after one hour from a time when the holding ability test is started. Helium gas is accommodated in a cavity defined by the base and the cover.

Abstract: A pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer and a substrate layer configured to support the pressure-sensitive adhesive agent layer. The pressure-sensitive adhesive layer has a storage modulus of 250 kPa or less at 23° C. The substrate layer has an elastic modulus of 1680 N/cm to 3000 N/cm both inclusive. The pressure-sensitive adhesive sheet shows a deviation amount less than 1.0 mm The amount is the deviation amount of the pressure-sensitive adhesive sheet per 250 gf/cm2 of the sheet in a holding ability test at 80° C. after one hour from a time when the test is started.

Abstract: A suspension board with circuit includes a metal supporting layer, an insulating base layer formed on the metal supporting layer, a conductive layer formed on the insulating base layer, and a slider supported on the metal supporting layer via a pedestal. The conductive layer includes a conductive overlapping portion which overlaps a plane on which the slider is projected when projected in a thickness direction. The conductive overlapping portion is provided to be spaced apart from the slider.
