As far as i understand it, IDE == ATA and ATAPI is scsi commands (command packets) over ATA. For a larger IDE/ATA explanation see:

ATA vs ATAPI vs IDE

That link gives a great explanation. For those not interested enough to read it all, I'd like to emphasize the most important part:

IDE is a very widely used misnomer for ATA. IDE is a technology in which a disk controller is packaged with the disks and heads. All modern disk drives, including SCSI, are IDE. ATA is a disk drive interface standard. But before the advent of SCSI, all IDE drives were ATA, so people accidentally picked up on the wrong name.

Indeed, the Linux module ide.o should have been named ata.o.
