Summary:To provide a disc device capable of suppressing the loss of airtightness at a welded area.SOLUTION: An HDD 10 includes a plurality of magnetic disks 12, a magnetic head 14, a housing 11, and a first protective member 41 made of resin. The magnetic disks have a recording layer. The magnetic head reads and writes information to and from the magnetic disks. The housing has a base 21 with an inner chamber in which the magnetic disks and magnetic head are housed, an outer cover 23 covering the inner chamber, and a welded area where the base and outer cover are welded. A first protective member is located outside the housing and covers at least a portion of the welded area.SELECTED DRAWING: Figure 2 【課題】溶接部において気密性が損なわれることを抑制可能なディスク装置を提供する。【解決手段】ＨＤＤ１０は、複数の磁気ディスク１２と、磁気ヘッド１４と、筐体１１と、樹脂製の第１の保護部材４１とを備える。磁気ディスクは、記録層を有する。磁気ヘッドは、磁気ディスクに対して情報を読み書きする。筐体は、磁気ディスク及び磁気ヘッドが収容される内室が設けられたベース２１と、内室を覆う外カバー２３と、ベースと外カバーとが溶接された溶接部とを有する。第１の保護部材は、筐体の外部に位置し、溶接部の少なくとも一部を覆う。【選択図】図２
