Recording medium capable of recording a first data-type and a second data-type, playback method and playback device for playing back from the recording medium, and recording device for recording first-type data and second type data on the recording medium

A reproducing device for reproducing data from a recording medium comprising:

• a first recordable area for recording first-type data composed of at least one program;
• a second recordable area for recording second-type data composed of at least one file;
• a third recordable area for recording second-type data composed of at least one file;
• a first management area for managing the at least one program of the first recordable area and at least one file of the second recordable area and a defective area on the medium, first management data comprising a corresponding part table indicating data for indicating a part table, the part table manages the start address, end address of part of a program, and link information for indicating next slot address to be linked;
• a second management area for managing the at least one file of the second recordable area;
• and
• a third management area for managing at least one file of the third recordable area, the reproducing device comprising:
• means for reproducing the first management data of the first management area;
• first determining means for determining whether or not a defective area is being managed within the first management data of the first management area reproduced by the reproducing means;
• first management means for, when determined by the first determination means that a defective area is being managed, accessing the defective area based on defective area management data;
• second determining means for determining whether or not an error exists at the accessed defective area;
• third determining means for determining whether or not there is a third management area when there is no error present at the defective area accessed by the second determining means:
• and
• second management means for, when the third determining means determines the existence of a third management area, reproducing contents of the third management area and accessing file data based on reproduced third management data.

A reproducing device for reproducing data from a recording medium comprising:

• a first recordable area for recording first-type data composed of at least one program;
• a second recordable area for recording second-type data composed of at least one file;
• a third recordable area for recording second-type data composed of at least one file;
• a first management area for managing the at least one program of the first recordable area and at least one file of the second recordable area, first management data comprising a corresponding part table indicating data for indicating a part table, the part table manages the start address, end address of part of a program, and link information for indicating next slot address to be linked;
• a second management area for managing the at least one file of the second recordable area;
• and
• a third management area for managing at least one file of the third recordable area, recorded at a position having an address offset by a prescribed extent from within the first management area, said reproducing device comprising:
• reproducing means for reproducing recorded information;
• arithmetic means for carrying out a prescribed operation based on an address of a first management area read-out by the reproducing means;
• and
• control means for accessing the first management area read-out by the reproducing means based on results of a calculation carried out by the arithmetic means and
• accessing file data based on third management data read out by the reproducing means.

A reproducing method for reproducing data from a recording medium having:

• a first recordable area for recording first-type data composed of at least one program;
• a second recordable area for recording second-type data composed of at least one file;
• a first management area for managing the at least one program of the first recordable area and at least one file of the second recordable area, and first management data comprising a corresponding part table indicating data for indicating a part table, the part table manages the start address and end address of part of a program, start address and end address of part of the second recordable area, and link information for indicating next slot address to be linked;
• and
• a second management area for managing the at least one file, the reproducing method comprising the steps of:
• reproducing the first management data from the first management area;
• determining whether or not second-type data has been reproduced from the first management area;
• accessing the management area in accordance with the first management data and reproducing the second management data when existence of the second-type data on the recording medium is determined;
• and
• reproducing file data in accordance with the second management data of the second management area.

A reproducing method for reproducing data from a recording medium having:

• a first recordable area for recording first-type data composed of at least one program;
• a second recordable area for recording second-type data composed of at least one file;
• a third recordable area for recording second-type data composed of at least one file;
• a first management area for managing the at least one program of the first recordable area, at least one file of the second recordable area and a defective area on the medium, first management data comprising a corresponding part table indicating data for indicating a part table, the part table manages the start address, end address of part of the part program or defective area, and link information for indicating next slot address to be linked;
• a second management area for managing the at least one file of the second recordable area;
• and
• a third management area for managing at least one file of the third recordable area, the reproducing method comprising the steps of:
• reproducing the first management data of the first management area;
• determining in a first determination step whether or not a defective area is being managed within the first management data of the first management area;
• accessing the defective area based upon the first management data when determined in the first determination that a defective area exists;
• determining in a second determination whether or not an error data exists in the accessed defective area;
• determining in a third determination whether or not a third management area exists in accordance with a result of the second determination;
• reproducing the third management data of the third management area when a third management area is determined to exist in the third determination;
• and
• accessing the at least one file data based on the reproduced third management data.
