[Expert] Burning restriction as regular user

[Miark]

I'm trying to use cdrecord from the commandline as a regular user, 
but it complains: 

cdrecord: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK limits.
cdrecord: Cannot allocate memory. WARNING: Cannot do mlockall(2). 
cdrecord: WARNING: This causes a high risk for buffer underruns. 
cdrecord: Operation not permitted. WARNING: Cannot set RR-scheduler 
cdrecord: Permission denied. WARNING: Cannot set priority using setpriority().
cdrecord: WARNING: This causes a high risk for buffer underruns.
scsidev: 'ATA:1,0,0' devname: 'ATA'
scsibus: 1 target: 0 lun: 0
Warning: Using badly designed ATAPI via /dev/hd* interface.
cdrecord: Permission denied. Cannot open '/dev/hda'. Cannot open SCSI driver. 
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root. 
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.

No problems with root. What's the simple solution?
