Record medium, and method for recording to and reproducing from a record medium

A method of reproducing successive data elements recorded as arranged data elements on a record medium in which each arranged data element includes data from two respectively different unarranged data elements, comprising the steps of:

• reproducing said successive arranged data elements from said record medium, each reproduced arranged data element having a plurality of data including error detection and error correction data;
• transferring some of the data in a reproduced arranged data element to a different reproduced arranged data element to produce rearranged data elements;
• detecting and correcting errors in each of said rearranged data elements in accordance with the error detection and error correction data in said rearranged data element;
• and
• supplying the error corrected rearranged data elements as unarranged data elements.

A method of reproducing data recorded as arranged data elements on a record medium, comprising the steps of:

• reproducing at least two arranged data elements from said record medium, each of said arranged data elements having a plurality of data including error detection and error correction data;
• identifying in each of the reproduced arranged data elements data therein which is associated with a single rearranged data element, said rearranged data element containing data derived from both of the reproduced arranged data elements;
• storing in a memory data included in a reproduced arranged data element which has been identified as being associated with said single rearranged data element and generating therefrom said single rearranged data element;
• detecting and correcting errors in the generated single rearranged data element in accordance with the reproduced error detection and error correction data;
• and
• supplying the error corrected single rearranged data element as an output.

A method of reproducing arranged data from a read-only, a writable or a hybrid record medium, comprising the steps of:

• identifying the record medium as a read-only record medium, a writable record medium or a hybrid record medium, the latter having both read-only and writable regions;
• identifying the read-only regions and the writable regions of said record medium when said record medium is identified as a hybrid record medium;
• reproducing from said read-only or writable region arranged data elements containing error detection and error correction data;
• transferring some of the data in a reproduced arranged data element to a different arranged data element to produce rearranged data elements when said data elements are reproduced from said read-only region;
• providing each of said arranged data elements as said rearranged data elements when said data elements are reproduced from said writable region;
• detecting and correcting errors in a rearranged data element in accordance with the error detection and error correction data in said each rearranged data element;
• and
• supplying the error corrected rearranged data elements as an output.
