(2) LBA mode
Logical address assignment in the LBA mode starts from physical cylinder 0,
physical head 0, and physical sector 1. If the last sector in a zone of a physical
head is used, the track is switched and the next LBA is assigned to the initial
sector in the same zone of the subsequent physical head.
After the last physical sector of the last physical head is used in the zone, the
subsequent zone is used and LBA is assigned from physical head 0 in the same
way.
Figure 6.6 shows an example of 4 heads configuration (assuming there is no track
skew).

6.3 Power Save
The host can change the power consumption state of the device by issuing a
power command to the device.
6.3.1 Power save mode
There are four types of power consumption state of the device including active
mode where all circuits are active.
In the power save mode, power supplying to the part of the circuit is turned off.
There are three types of power save modes:
•
Idle mode
