Abstract
A method, medium, and apparatus transforming a logical address of a disc. The method includes mapping a plurality of physical addresses to a plurality of logical addresses with reference to the data transmission speeds of the heads so that a physical address for a head having a higher data transmission speed is mapped to a relatively lower logical address, and transforming logical addresses of the disc drive into physical addresses with reference to the mapping results. Accordingly, it is possible to minimize fluctuations in the data transmission speed of the disc drive whenever the disc drive switches heads.
Claims17
A method of transforming an address of a disc drive, the method comprising:
- mapping a plurality of physical addresses to a plurality of logical addresses, with reference to data transmission speeds of heads of the disc drive, so that a physical address for one head having a higher data transmission speed than another head is mapped to a lower logical address than the head having the lower data transmission speed;
- and
- transforming logical addresses of the disc drive into physical addresses with reference to the mapping of the plurality of physical addresses to the plurality of logical addresses.
A disc drive, comprising:
- a plurality of heads, each having different data transmission speeds;
- and
- a controller to transform, with reference to the data transmission speeds of the heads, a lower logical address for one head into a physical address for the one head, the one head having a higher data transmission speed than another head.
A disc drive controller to transform, with reference to the data transmission speeds of read/write heads, a lower logical address for one head into a physical address for the one head, the one head having a higher data transmission speed than another head.
A method of recording and/or reproducing data based on a transforming of an address of a recording and/or reproducing apparatus, wherein a mapping of a plurality of physical addresses to a plurality of logical addresses, with reference to data transmission speeds of heads of the recording and/or reproducing apparatus, has been mapped such that a physical address for one head having a higher data transmission speed than another head is mapped to a lower logical address than the other head having the lower data transmission speed, the method comprising:
- recording and/or reproducing data from a medium based on the mapped addresses.
