Embodiment
The present invention is further elaborated with reference to the accompanying drawings and examples.
In the present embodiment, the Seagate hard disk without digital-to-analogue conversion parameter DAC has been selected.
As shown in figure 1, a kind of method for the magnetic head read or write speed for improving Seagate hard disk, comprises the following steps:
S100:Obtain the ROM file of Seagate hard disk:The hard disk is connected with computer, obtain the hard disk handle and to
The hard disk sends the instruction for obtaining ROM, in the present embodiment, by com port pattern acquiring to the hard disk ROM file, can also lead to
Cross ATA pattern acquiring ROM files.
S200:The address realm of reading adaptation parameter RAP in ROM file is determined, includes following steps as shown in Figure 2:
S201:In the range of the initial address 0x00000000 to address 0x0000009F of ROM file, search and read adaptation ginseng
Number RAP mark 0x06, as shown in underscore part in Fig. 3；
S202:Read mark 0x06 after continuous three byte content, as read adaptation parameter RAP initial address, this
Beginning, address was with the storage of small end form:As shown in rectangle frame part in Fig. 3, because the initial address is with the storage of small end form, so
Initial address is 0x075000；
S203:Mark 0x06 redirects five bytes backward, to redirect the current address after five bytes as initial address, the company of reading
End addresses of the content 0x00F007 of continuous three bytes as reading adaptation parameter RAP, as shown in oval frame part in Fig. 3, due to
The end address is stored with small end form, so end address is 0x07F000.
S300:Gap parameter Clearance value is obtained, includes following steps as shown in Figure 4:
S301:Perform the multiple parameters that F3 orders obtain the hard disk；
S302:As shown in figure 5, gap parameter Clearance mark AFH Head/Zone are found in multiple parameters
Parms；
S303:As shown in figure 5, obtain W+HtClr, RHtClr in gap parameter Clearance, PrhtClr,
TargWrClr and TargPreClr value, wherein, W+HtClr represents hot write gap parameter, and RHtClr represents that heat reads gap ginseng
Number, PrhtClr represent preheating gap parameter, and TargWrClr is represented to write mark gap parameter, and TargPreClr is represented between preliminary making
Gap parameter；
As shown in figure 5, in the present embodiment, by taking User Zone 00 gap parameter Clearance as an example, W+HtClr,
RHtClr, PrhtClr, TargWrClr and TargPreClr value are respectively 0x64,0x60,0x61,0x12,0x12.
S400:Searched in the address realm for reading adaptation parameter RAP and rewrite gap parameter Clearance value, comprising
Following steps as shown in Figure 6:
S401:W+HtClr, RHtClr, PrhtClr, TargWrClr are searched in the address realm for reading adaptation parameter RAP
And TargPreClr value, i.e. initial address 0x075000, end address 0x07F000, W is searched in the range of this address
+ HtClr, RHtClr, PrhtClr, TargWrClr and TargPreClr value, that is, search 0x6460611212, as in Fig. 7
Location is shown in 0x0007D220 to 0x0007D224 underscore part；
S402:In this implementation, by W+HtClr, RHtClr, PrhtClr, TargWrClr and TargPreClr value 0x64,
0x60,0x61,0x12,0x12 each increase 0x10, i.e. are rewritten as 0x74,0x70,0x71,0x22,0x22；The increased value of institute
Integral multiple for 0x10 and it is not more than 0x30；
S403:Judge whether to complete all W+HtClr, RHtClr, PrhtClr, TargWrClr and TargPreClr weight
Write, if it is, performing step S500, otherwise perform step S402.
S500:Verify ROM file and be written back to ROM file and change hard disk.
By the above method, the read or write speed of Seagate hard disc magnetic head, which has, to be significantly improved.
It should be appreciated that the invention is not restricted to above-mentioned citing, for those of ordinary skills, can basis
Described above is improved or converted, and all these modifications and variations should all belong to the protection model of appended claims of the present invention
Enclose.
