In order to provide a protective cover (2) for an objective (7) of an optical head (9), which can be used both when the optical head is installed and during its production and transport and, in addition, is also suitable for recording and reproducing apparatus which, during the operation of the apparatus, is able to provide only a small spacing between the optical head (9) and the optical recording medium, a protective cover (2) for an objective (7) of an optical head (9) is proposed which can be moved between a position covering the objective (7) and a position exposing the objective (7). The protective cover (2) can be locked both in the position covering the objective of the optical head and in the position exposing the objective, so that the protective cover can be used not only when the optical head is installed but also during its production and transport. In the position exposing the objective, the protective cover (2) is positioned outside the plane between the optical head (9) and an optical recording medium located opposite the optical head, in order to permit the use of this protective cover even in recording and/or reproducing apparatus whose available space is limited, in particular between the optical head and optical recording medium. |
