Detailed Description

The MSF structure allows you to translate blocks to minute, second and frame (MSF) interval This structure should not be used to calculate the Logical Block Address.

Use the LBA structure to translate from LBA to minute, second, frame and vice versa.

LBA Minutes Seconds Frames. One frame is 1/75 of a second or the size of a CDDA block (2352 bytes). Returns the length in blocks of a MSF (Min, Second and Frame) interval. The calculation is done according to the following formula:

blocks = (min * 60 + sec) * 75 + frame Returns the MSF (Min, Second and Frame) interval which corresponds to a given number of blocks.

The calculation is done according to the following formula:

//                      min   = blocks / 60 / 75
//                      sec   = (blocks - min*60*75) / 75
//                      frame = (blocks - min*60*75 - sec*75
//              

The LBA structure allows you to translate logical block address to minute, second and frame (MSF) address This structure should be used to calculate the Logical Block Address only.

MSF Minutes Seconds Frames. One frame is 1/75 of a second or the size of a CDDA block (2352 bytes). Translates a MSF Address to Logical Block Address. This method corrects the resulting LBA according to the CDDA standard.

The following formula is used for calculating the LBA:

//                      lba = (min * 60 + sec) * 75 + frame
//                      if (min < 90) lba = lba - 150 else lba = lba - 450150
//              

Returns the Minute, Second, Frame address from a logical block address.

The following formula is used for calculating the minutes, seconds and frames:

//                      if (lba >= -150) 
//                      {
//                              min = (lba + 150) / 60 / 75;
//                              sec = (lba + 150 - min*60*75)  / 75;
//                              frame = (lba + 150 - min*60*75 - sec*75);
//                      } 
//                      else if (lba >= -45150 && lba <= -151) 
//                      {
//                              min = (lba + 450150) / 60 / 75;
//                              sec = (lba + 450150 - min*60*75)  / 75;
//                              frame = (lba + 450150 - min*60*75 - sec*75);
//                      } 
//
