同様である。2. Description of the Related Art It is common for a servo access system to include a notch filter in order to dampen the M resonance of a magnetic disk device ft,i. The same applies to a magnetic disk device in which an assembly (head-disk assembly) in which a disk, a head positioning mechanism, etc. are integrated is replaceable.

るものである。However, a conventional magnetic disk drive 1llt in which the head disk assembly is replaced with an "IK", as shown in FIG. are mounted on the printed circuit board on the side of the main body of the magnetic disk assembly 4 from which the head disk assembly 4 is delaminated.Incidentally, 5 is a carry run movable part, 6 is a servo head, 7e is a servo disk, and 8 is a part of the servo head 6. This is a starting signal and is manually input to the position demodulator l.
このような構成であると、次のような問題がある。Such a configuration has the following problems.

ツチフィルタの＃１４整のために、ヘッドディスク組立
体の交換に伴うダウン時間か増大する。Every time the entire head disk assembly is replaced, an AM with a notch filter at a dead-phase frequency is required. For this adjustment, it is necessary to measure with high precision the natural mechanical vibration frequency of the moving part of the carry run for each head tisf assembly, or to ensure a constant tn11 degree at the location where the magnetic disk drive is installed. It is generally impossible to do this, and positioning accuracy is likely to deteriorate due to notch filter adjustment errors. Also,
The carriage movable part is solid 1! Measuring the mechanical vibration cylinder wave number and adjusting #14 of the notch filter increase the downtime associated with replacing the head disk assembly.

クセス糸全構成する。In the figure, 4' is a replaceable head disk assembly. The notch filter 2, which is a factor constituting a servo access thread similar to the conventional one, is not provided on the magnetic disk device main body side, but is provided on the head disk assembly 4' side. When the head disk assembly 4' is attached to the magnetic disk drive main body, the notch filter 2 is connected to the connector 9.
The entire hobo access yarn is connected as shown through the conventional hobo access thread.

高い位置決め確度を維持できる。With such a configuration, by setting the attenuation frequency of the notch filter optimally in each of the magnetic TiSF assemblies (there are two) in the 14-stage adjustment process at the manufacturing plant, the head can be easily adjusted when installing the magnetic TiSF device. It is no longer necessary to adjust the notch filter when replacing the disk assembly, and the down time associated with replacing the head disk assembly can be greatly reduced. Because it is possible to measure the natural mechanical vibration frequency of the moving part of the shaft for each disk assembly to a total height of n degrees, and adjust the notch filter to a high f# degree,
High positioning accuracy can be maintained.
