Title: Magnetic disk device
Inventor: SATOU TAKAKORE
IPC: G11B21/21
Filed: 1979-12-25
Abstract: PURPOSE: To avoid a difference of record density between the outer and inner parts of a magnetic disk, by setting the seeking direction of the magnetic head so as to secure a fixed angle to the center of the spindle of the magnetic disk.  
     CONSTITUTION: The magnetic disk device has the double-body type slider plus a magnetic head containing the record/reproduction core provided on the one side floating surface of the slider. For such disk device, the seeking direction of the magnetic head 2 is set so as to secure a fixed angle to the center of the spindle of the magnetic disk 1. As a result, the floating balance of the head 2 lost largely toward the inner side and the floating amount is reduced at the part 5 where the magnetic head core exists. Thus an even output reproduction waveform can be obtained at both the inner and outer sides of the magnetic disk. As a result, a wide dynamic range becomes unnecessary for the reproduction circuit system especially for the AGC circuit.
