ABSTRACT:
A photosensor block for use with a zero track sensor of a disk drive unit or the like wherein adjustment of the position of a photosensor can be effected simply with accuracy. In the photosensor block, a photosensor forms a side of a deformable parallelepiped and is mounted on a mounting member having a pair of parallel elastic members which form a pair of opposing sides of the parallelepiped. An interconnecting portion of the mounting member between the elastic members is secured either to the photosensor or to a base member which is mounted on a stationary section of the unit and forms the remaining side of the parallelepiped. Opposite ends of the elastic members are removably connected to the other of the photosensor and the base member. An adjusting member is adjustably mounted on the base member for pressing against a side face of one of the elastic members for fine adjustment of the position of the photosensor.
