Pre-Amplifier for Hard Disk Drive with
MR-Read / Inductive Write Heads
TDA5360

- Temperature digitizer
This measurement can be done either in Active Read mode or in Active Write mode.
Note 9a : RSTDMY define DRN pin functionality
Note 9b : MODE1,MODE0 power management control bits
- Test mode is a state where both Reader and Writer are ON when R/W pin is LOW : in write mode, reader
signal is present at RDP-RDN output pins.
- (A2=A1=1 and STWN=0) is a broadcast mode condition, where all the preamps will treat the data arriving on
SDATA line.
- In order to get two write head selected, Head Hx should be programmed in Reg. 00 (x = 0 to 5). In that case
Head Hx and Head H(x+6) will be selected in STW (Servo Track Write) 2 heads.
Note 11a : ENFST define BFAST pin functionality when Thermal Asperity Compression is ON

Note 11b : Thermal Asperity Compression ( TAC ) functionality
When a thermal asperity occurs at the reader input, the reader output signal get superposed with an amplified
signal corresponding, to a certain extent, to the thermal asperity.
