Abstract
PURPOSE: To secure the reproduction from the disk to which the recording is given with a high recording air pressure with a high S/N and reduced fluctuation of the signal level by giving a special consideration to the location state of the pickup arm to which the signal scanner is stuck for the recording and reproduction of the non- groove disk.
CONSTITUTION: Scanner needle S to read out the information signal in the record tracks of disk D is stuck to pickup arm P so that the agreement may be obtained between the width direction of electrode part 1 and that of the recording track. Both legs 16a and 16b of arm P are formed into the rigid 2-prong shape with a bridge secured by attachment main body 35. And pivot 16a1 at the base tip part is pressed to pivot holders 9A and 9B at the mobile part procided at driving device DA to connect arm P to device DA. As a result, arm P can give an easy displacemet to needle S following the plane deflection of disk D, and also the tracking control is given through the displacement of needle S in the extension direction of arm P via the 2-dimensional driving of device DA. At the same time, the jitter correction is given by displacement of needle S in the extension direction of the record track.
