... Application notes for TZA1000 and SZA1000. Both are available from Philips Semiconductors. GENERAL DESCRIPTION The TZA1000 is a single-chip read-write amplifier for single-channel QIC (Quarter Inch Cartridge) systems with MR heads. It can be used with both SIG (Sensor in Gap)- and yoke-type MR heads and is designed to be used in conjunction with the Philips SZA1000 digital equalizer IC (although it can also function as a stand alone unit) ...

... G6DB bit in the control register via the serial interface (see Table 13). The AGC is frozen while the HOLD input is LOW, the TZA1000 is writing, or the servo mode. The AGC can be operated internally, running on the CLK clock signal on pin 15 (HOLD HIGH and GFXD LOW; see Table 12), or externally by means of a software algorithm (GFXD HIGH) ...
