Abstract
A data allocation control method is applicable to a data recording apparatus for writing and/or reading data to/from a recording surface of a disciform recording medium. In this method, data to be recorded on the recording surface is divided into a plurality of data blocks to be consecutively dealt with. Next, allocation information for designating each location of the plurality of data blocks is generated such that a second data block next to a first data block included in the plurality of data blocks is located to keep a predetermined interval from a location of the first data block.

A data allocation control method applicable to a data recording apparatus for writing and/or reading data to/from a recording surface of a disciform recording medium, the method comprising the steps of:
- dividing data to be recorded on the recording surface into a plurality of data blocks to be consecutively dealt with;
- and
- generating allocation information for designating each location of the plurality of data blocks, such that a second data block next to a first data block included in the plurality of data blocks is located to keep a predetermined interval from a location of the first data block.
A data allocation control method applicable to a data recording apparatus for writing and/or reading data to/from a recording surface of a disciform recording medium, the method comprising the steps of:
- dividing data to be recorded on the recording surface into a plurality of data blocks to be consecutively dealt with;
- generating first allocation information for designating a location of a first data block included in the plurality of data blocks;
- and
- generating second allocation information for designating a location of a second data block next to the first data block, such that the second data block is located to keep a predetermined interval from the location of the first data block.
A data allocation control method applicable to a data recording apparatus for executing positioning control by rotating a disciform recording medium and by moving the head in a radial direction of the recording medium, and for writing and/or reading data to/from a recording surface to which the head is positioned, the method comprising the steps of:
- dividing data to be recorded on the recording surface into a plurality of data blocks to be consecutively dealt with;
- generating first allocation information for designating a location of a first data block included in the plurality of data blocks;
- generating second allocation information for designating a location of a second data block next to the first data block, such that the second data block is located to keep a predetermined interval from the location of the first data block;
- and
- controlling to move the head to each of the locations designated by the first and second allocation information.
A data allocation control method applicable to a data recording apparatus for writing and/or reading data to/from a recording surface of a disciform recording medium, the method comprising the steps of:
- dividing data to be recorded on the recording surface into a plurality of data blocks to be consecutively dealt with;
- and
- generating size information for designating the size of each data block, such that the data block to be located in a region where access speed is higher has a large size and the data block to be located in a region where the access speed is lower has a small size.
A disciform recording medium applicable to a data recording apparatus for writing and/or reading data to/from a recording surface of the recording medium, data allocation for the recording medium comprising the steps of:
- dividing data to be recorded on the recording surface into a plurality of data blocks to be consecutively dealt with;
- and
- generating allocation information for designating each location of the plurality of data blocks, such that a second data block next to a first data block included in the plurality of data blocks is located to keep a predetermined interval from a location of the first data block.
A disciform recording medium applicable to a data recording apparatus for writing and/or reading data to/from a recording surface of the recording medium, data allocation for the recording medium comprising the steps of:
- dividing data to be recorded on the recording surface into a plurality of data blocks to be consecutively dealt with;
- generating first allocation information for designating a location of a first data block included in the plurality of data blocks;
- and
- generating second allocation information for designating a location of a second data block next to the first data block, such that the second data block is located to keep a predetermined interval from the location of the first data block.
A disciform recording medium applicable to a data recording apparatus for executing positioning control by rotating the recording medium and by moving the head in a radial direction of the recording medium, and writing and/or reading data to/from a recording surface to which the head is positioned, data allocation for the recording medium comprising the steps of:
- dividing data to be recorded on the recording surface into a plurality of data blocks to be consecutively dealt with;
- generating first allocation information for designating a location of a first data block included in the plurality of data blocks;
- generating second allocation information for designating a location of a second data block next to the first data block, such that the second data block is located to keep a predetermined interval from the location of the first data block;
- and
- controlling to move the head to each of the locations designated by the first and second allocation information.
A data server apparatus applicable to a data recording apparatus for writing and/or reading data to/from a recording surface of a disciform recording medium, the data server apparatus comprising:
- means for dividing data to be recorded on the recording surface into a plurality of data blocks to be consecutively dealt with;
