摘要:
A video tape recorder capable of reproducing a video tape on which a character multiplex signal is recorded. In the video tape recorder, when a video tape recorder unit reproduces the video tape, a character signal generator generates a character display signal based on the character multiplex signal. When the video tape recorder unit is transferred from the reproduction operation to a pause operation, the character signal generator continues generating the character display signal which has been generated immediately before the transfer to the pause operation.
摘要:
A television receiver with a video tape recorder, in which a common terminal of an external-input changeover switch is connnected to one input terminal of a first changeover switch via an AGC circuit, the other input terminal is connected to an output of a video signal reproducing circuit, and a common terminal of the first changeover switch is connected to a television signal processing circuit. Further, a second changeover switch is interposed between the common terminal of the first changeover switch and the television signal processing circuit, one input terminal of the second changeover switch is connected to an input terminal side of the AGC circuit, the other input terminal is connected to the common terminal of the first changeover switch, and the common terminal is connected to the television signal processing circuit. Furthermore, a switch circuit is disposed which controls the first and second changeover switches so as to be operated in an interlocked manner.

摘要:
Embodiments in accordance with the present invention relate to improving error recovery process performance. A head slider in an embodiment of this invention includes a heater for adjusting a clearance between a head element section and a magnetic disk. During an error recovery process (ERP) for a reading error, if a particular environmental temperature is in a low-temperature region, a microprocessing unit (MPU) executes the ERP steps of increasing a heater power value of the heater (i.e., STEP X to STEP X+2), preferentially over the ERP steps of reducing the heater power (i.e., STEP X+3 to STEP X+5). In the low-temperature region, the possibility of error recovery in an earlier step can be raised by executing the heater power increasing ERP steps earlier than the heater power reducing ERP steps.
