Description

[Brief explanation of drawings]

FIG. 1 is a diagram showing a schematic configuration of a forced recording circuit device in an information recording apparatus which is an embodiment of this invention. FIG. 2 is a diagram schematically showing the overall structure of a tape cassette, which is an example of a recording medium having an error erasure prevention section. FIG. 3 is a diagram showing a schematic configuration of a state detection section of an error erasure prevention section of a recording medium and a recording signal generation section in a conventional information recording apparatus. FIG. 4 is a diagram showing an example of a configuration for generating an internal recording signal for activating an information recording system in a conventional information recording apparatus. FIG. 5 is a diagram showing an example of a conventional method for restoring a recording medium in a write-inhibited state to a recordable state. A covered state is shown as an example. In the figure, 10 is a tape cassette which is a recording medium, 11 is a magnetic tape which is a recording medium, 13 is a cassette case, 13 is an error erasure prevention section, 14 is an error erasure prevention claw, and 15 is a tape for repairing the error erasure prevention section. , 20 is a cassette switch for detecting the recordable/inhibited state of a recording medium such as a tape cassette, 21 is a recording switch for generating a recording instruction signal, and 22 is responsive to signals from the cassette switch 20 and the recording switch 21. 23 is a tape drive mechanism for driving a tape as a recording medium; 30 is a logic gate for generating an internal recording instruction signal; and 41 is a forced recording instruction. A forced recording switch 42 for generating a signal is a forced recording circuit that generates a signal for forcibly making a recording medium in a recordable state into a recordable state. In addition, in the figures, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Claims for Utility Model Registration] A circuit device for making it possible to record information on a recording medium equipped with an error erasure prevention section having a recording inhibit signal generation function, the circuit device detecting the state of the error erasure prevention section. a first means for generating a signal thereby indicating whether information can be recorded on the recording medium; a second means for generating a signal for instructing forced recording on the recording medium; and third means for disabling the output of the first means and generating a signal indicating that the recording medium is in a recordable state in response to a forced recording instruction signal from the means. forced recording circuit.
