Embodiment 1

[0085] There is data to be written that needs to be written into the hard disk of the electronic device, and the current first position of the magnetic head in the hard disk can be determined.

[0086] After the first position is determined, the first track whose distance from the first position is not greater than the first preset distance may be determined.

[0087] In this embodiment, there may be more than one first magnetic track whose distance from the first position is not greater than the first preset distance. For example, a plurality of first magnetic tracks may be determined and selected one of the first tracks, and determine the first address corresponding to the selected first track.

[0088] In this embodiment, when selecting from a plurality of the first magnetic tracks, one of the first magnetic tracks can be selected arbitrarily, or all the first magnetic tracks with the shortest distance to the first position can be selected. the first track, or select a spe...

Embodiment 3

[0107] There is data to be written that needs to be written into the hard disk of the electronic device, and the current first position of the magnetic head in the hard disk can be determined.

[0108] After the first position is determined, the first track whose distance from the first position is not greater than the first preset distance may be determined.

[0109] In this embodiment, there may be more than one first magnetic track whose distance from the first position is not greater than the first preset distance. For example, a plurality of first magnetic tracks may be determined and selected one of the first tracks, and determine the first address corresponding to the selected first track.

[0110] In this embodiment, when selecting from a plurality of the first magnetic tracks, one of the first magnetic tracks can be selected arbitrarily, or all the first magnetic tracks with the shortest distance to the first position can be selected. the first track, or select a spe...

Abstract

The invention discloses a data writing method which is used for increasing the data writing speed. The data writing method includes determining first magnetic tracks in hard disks when first to-be-written data need to be written into the hard disks of electronic equipment, and determining first addresses corresponding to the first magnetic tracks; acquiring second addresses corresponding to the to-be-written data; creating first mapping relations among the second addresses and the first addresses when the first addresses are different from the second addresses; writing the to-be-written data into positions directed by the first addresses so that the to-be-written data can be read from the first addresses according to the first mapping relation when needed. The distances from the first magnetic tracks to current first positions of magnetic heads are not farther than first preset distances. The invention further discloses the electronic equipment for implementing the data writing method.

Description

technical field [0001] The invention relates to the fields of computer and communication, in particular to a method for writing data and electronic equipment. Background technique [0002] In the prior art, when writing data into HDD (Hard Disk Drive, hard disk drive), the time for writing data includes three parts: the time for the magnetic head to find the track, the time for waiting for the hard disk to turn to the corresponding track, and the time for writing data. time. Because the time for the magnetic head to search for the track and the time for waiting for the hard disk to turn to the corresponding track may be longer, the rate of writing data to the HDD in the prior art is relatively slow and the efficiency is low. [0003] To solve this problem, a solution is adopted in the prior art: write the data to be written into the hard disk into a flash (flash memory), which is equivalent to directly shortening the time for the magnetic head to find the track and waiting ...
