Hitachi C4K60 - Travelstar Slim - Hard Drive Specifications page 15

*1 :Average time of seek is calculated under the following condition. (Read/Write ratio: Read only)
Average of 10,000 random seeks, Voltage 3.3V, Temperature 25°C.
Full stroke time of seek is calculated under the following condition.
Average of 1,000 full stroke seeks, Voltage 3.3V, Temperature 25°C.
This maximum time is not included the seek time by seek retry.
*2 :Periodically, during start up, the drive may perform a spin up retry operation. When this operation occurs,
the start up sound will change slightly and the ready timing will also be altered from typical time.
*3 :Power on to Ready time could take up to 10 seconds in case of spin up retries under certain
conditions of the voltage specifications(Table 3.1) and environmental specifications(Table 3.2).
*4 :For DC power input, the average current is measured at the connector of the PCBA of this drive and in
the nominal condition in which the power voltage and the temperature are 3.3V and 25°C, respectively.
The DC power input has to be burst free (common mode). The average current may have some
tolerance after power-on. The current measurement is recommended at 5 minutes later after power-on.

*5 :10ms averaged peak. For more information, refer to Section 6.1.
*6 :This value is at Low Power Idle mode. The heads are unloaded.
*7 :Power mode automatically enters to Active Idle mode after Read/Write operation.
*8 : Measured during random seek at the rate of three seeks per 100 msec.
*9 :Measured while reading or writing 16 sectors of data located on the same track.

Voltage rise time 5 - 100 ms at power on is required for power supply. The power
supply voltage must not be under –0.3V at power off.
