At this time, the stopper 50 is installed to extend upward from the base plate 10 is configured to limit the rotation of the cover support member 32 that rotates with the protective cover 31. This configuration is such that the position where the protective cover 31 covers the outer surface of the disk 1 through the stopper 50 can always be constant, and the protective cover 31 is excessively rotated due to external influences to prevent the disk ( This is to prevent the problem that causes the damage of 1).

The following describes the overall operation and usage of the recording apparatus for manufacturing a hard disk drive according to the present invention having such a configuration.

In order to perform a format operation for forming tracks and sectors on the manufactured disk 1, first, a plurality of disks 1 are inserted into the spindle 11 and combined. At this time, each disk 1 is laminated in a state spaced apart by a predetermined interval through the spacer member 14 mounted on the outer surface of the spindle 11, and finally by fastening the fixing member 13 to the upper end of the spindle 11 The disk 1 is fixed to the spindle 11 without flow.

After the mounting of the disk 1 is completed, the cover driving motor 41 is operated to cover the outer surface of the disk 1 while the protective cover 31 rotates toward the disk 1. At this time, the rotation link 42 is rotated by the drive of the cover drive motor 41, the cover support member 32 connected through the connecting shaft 43 and the long hole 36 by the rotation of the rotation link 42 is By rotating, the protective cover 31 rotates to cover the outer surface of the disk 1. When the protective cover 31 covers the outer surface of the disk 1, the stopper 50 further restricts the rotation of the protective cover 31 to protect the disk 1, and the detection sensor 45b rotates. By detecting the sensing piece 42a of the link 42, the rotation of the cover driving motor 41 may be stopped.

In this state, the protective cover 31 covers the outer surface of the disk 1 with the upper plate 31a and the lower plate 31b spaced apart from the disk 1, and the upper plate 31a and the lower plate ( The partition plate 31d between 31b) enters the spaced space between each disk 1 to partition the space between each disk 1 in the state spaced apart from each disk 1.

After the protective cover 31 covers the disk 1, the spindle 11 rotates at high speed by driving the spindle motor 12, and the high speed rotation of the disk 1 is performed. The recording head 24 records data on the disk 1 while moving on the surface of each disk 1 through the reciprocating rotation of. That is, it performs formatting.

At this time, the disk 1 that rotates at a high speed is rotated in a wrapped state through the protective cover 31, so that the disk 1 is protected from the flow of surrounding air due to the high speed rotation, thereby enabling stable rotation and accurate data recording. That is, since the resistance due to the flow of the ambient air through the protective cover 31 can be minimized, the disk 1 is not shaken, thereby minimizing data recording errors.

When the format of the disk 1 is completed, the drive of the spindle motor 12 stops, and at the same time, recording of data through the recording head 24 also stops. In addition, the protective cover 31 is rotated in the reverse direction through the reverse rotation of the cover drive motor 41 is spaced apart from the disk (1). When the protective cover 31 is completely opened from the disk 1, the rotation link 42 is detected by the detection sensor 45a and the rotation of the cover driving motor 41 is stopped. In this state, the user only needs to release the fixing member 13 coupled to the spins 11 to separate the disk 1 coupled to the spindle 11.

As described above, since the present invention can record data on the disk 1 in the state before assembling the hard disk drive, the present invention can reduce the manufacturing time of the hard disk drive when it is applied to the production line for manufacturing the hard disk drive. After the disk drive is assembled, a separate disk formatting process is not required, thereby reducing the size of the production facility for manufacturing the hard disk drive.

As described in detail above, the disk recording apparatus for manufacturing a hard disk drive according to the present invention has the effect of speeding up the production speed of the hard disk drive because data can be recorded on the disk in a state before assembly of the hard disk drive. .

In addition, since the present invention performs the operation of recording data on the disk at the pre-assembly stage of the hard disk drive, a separate disk format process is not required in the process after the assembly of the hard disk drive is completed. The effect is to reduce the size of the installation.

In addition, the present invention has the effect of minimizing the recording error because the disk is prevented from shaking because the disk rotating at high speed through the protective cover in the process of recording data on the disk is protected from the flow of ambient air.
