Positioning apparatus and a controlling apparatus

Abstract

There is provided a testing apparatus for inspecting a head and/or a disk. The testing apparatus includes a positioning apparatus that relatively positions the head and the disk and a controlling apparatus for controlling the positioning apparatuses. The positioning apparatus includes a linear positioning apparatus and a rotational positioning apparatus. The controlling apparatus comprises: a first processor for generating a first command relating to the dynamic positioning of the head or the disk in order to control the rotational positioning apparatus, and a second processor for generating a second command relating to the static positioning of the head or the disk in order to control the linear positioning apparatus. The first and second processors may be the same or different processors.

       12 . A testing apparatus for inspecting at least one of a head and a disk, said testing apparatus comprising: 
 a positioning apparatus that relatively positions said head and said disk, said positioning apparatus comprising a linear positioning apparatus and a rotational positioning apparatus; and    a controlling apparatus for controlling said positioning apparatuses, said controlling apparatus comprising: a first processor for generating a first command relating to a dynamic positioning of said head or said disk in order to control said rotational positioning apparatus, and a second processor for generating a second command relating to a static positioning of said head or said disk in order to control said linear positioning apparatus;    wherein said first and second processors may be the same or different processors.    
   
   
       13 . The testing apparatus according to  claim 12 , wherein said first command is a command representing sin −1 {dr/(L·cos φ)} or {dr/(L·cos φ)}, wherein the desired movement distance of said head is dr, the skew angle of said head is φ, and the distance between the center of rotation of said rotational positioning apparatus and said head is L.
